A Y-piece that puts a washing machine drain hose and a heat pump dryer condensate hose down one 33 mm sink drain hole that only has room for one of them. It drops into the hole and both hoses drop into it; nothing is sealed or clamped, so the air gap the washing machine needs stays, a back-up spills into the sink instead of the machine, and everything lifts straight out.

• Spigot ⌀33.21 × 80 mm into the ⌀33.61 hole (measured with callipers), a 0.2 mm radial clearance with a 1 mm lead-in chamfer at the bottom. The first print used 0.5 mm against a nominal ⌀33 and rattled, a real gap of 0.81 mm per side; 0.2 mm still drops in and lifts out. The spigot is long so the adapter stands square in the hole, and the drain has at least 150 mm of clear space below the rim. Above it sits a 45° collar that seats on the hole’s rim (self-centring, prints without support) and runs out to ⌀40.
• Washing hose socket: vertical, ⌀26.65 (the hose’s 25.65 + 0.5 mm per side), 35 mm deep, 1 mm lead-in at the rim. The hose stops on a shoulder where the socket narrows to the ⌀24 through bore — smaller than the hose’s outside so it cannot fall through, bigger than its ~20 mm inside so nothing chokes the flow.
• Dryer hose socket: a second vertical tube right beside the main one, sharing a 2.4 mm wall with it, ⌀(hose + 0.8 mm) with the same 2.7 mm outer wall, 28–30 mm deep (at least 27; both sockets end at one flat rim). It too stops on a shoulder (1 mm per side), and from there a narrower passage runs down, bends smoothly (10 mm centreline radius) to 45° and enters the main bore 1 mm or more below the washing hose’s end, so the dryer’s trickle joins the flow under the washing hose rather than around it. A web fills the notch between the two tubes so the passage stays inside the walls.
• Everything wider than the spigot — the collar, the dryer tube and the web — sits on one flare rising from the spigot’s top: 45° where it forms the collar’s seat, then curving on a 12 mm radius to vertical just clear of the dryer tube. The outside is therefore a continuous curve from the collar up into the twin tubes with no crease, the dryer tube still floats 2.4 mm or more above the sink, and nothing overhangs when printed.
• Main tube ⌀33.21 throughout (3.3 mm wall round the washing socket, 4.6 mm round the bore).

A 1U insert for 10" mini racks (Project MINI RACK / DeskPi / GeeekPi style cabinets) that turns the top of the rack into a status display and fan controller. A 480×128 bar TFT sits in the middle of the faceplate; a Raspberry Pi Zero 2 W behind it drives the screen over SPI and a 180 mm PWM fan over a 4-pin header, reads the fan’s tacho and a couple of temperature probes, and shows the lot. A rocker, a knob and a USB keystone port sit in a row beside the screen, the port wired to the Pi’s own USB for a keyboard or a stick without opening the rack.

The fan is the design. A 180 × 180 × 40 mm fan hung from the cabinet’s top plate and centred in a 245 mm-deep rack fills Y 32.5…212.5 and all but 4.45 mm of the U’s height. So this insert takes the front 32.5 mm and nothing else — no floor under the fan, where a shelf would foul it and choke its air. Everything lives in a 29 mm-deep open-backed box, leaving 3.5 mm of clear air in front of the blades. The fan cannot be set back to buy room either: at 180 mm deep it already spans the gap between the rack’s front and rear legs.

Why this display. It is a Crystalfontz CFAF480128A0-039TN-A1-1, a 105.50 × 37.00 × 10.73 mm module whose Bridgetek EVE chip drives the graphics, backlight and audio over SPI. Its controller is on the module, which is the whole point: a 7" 280×1424 bar would span the rack front far more handsomely, but it needs a separate 55 × 45 mm HDMI board, and 45 mm goes nowhere in a 1U shared with a 180 mm fan — not upright, not flat, not tilted at any angle, and 45 mm exceeds the 44.45 mm U itself.

How it holds together. The module’s front face seats 2 mm into a rebate in the back of the faceplate and the rest stands proud into the bay. The tray’s top and bottom walls are exactly the module’s height plus 0.4 mm apart, so they are its guides; four corner nubs locate it sideways, the bezel holds it forward, and two full-length ribs on the rear cover press it back. The bezel laps 0.3 mm of the active area all round, so nothing ever shows the module’s frame.

The cover is the electronics tray. Four bosses take the Pi, four more a 12 V → 5 V converter, and four countersunk M3 screws hold the whole thing onto posts standing off the back of the faceplate — flush, because that is all the room the fan leaves. Undo four screws and the electronics lift out together. Cables leave through a notch at the rear of each side wall into the channels beside the fan; floor, roof and both side walls carry pointy-top honeycomb (nominal 7 mm holes on 2 mm ribs).

Why the USB port is at the end. A USB keystone coupler is about 35.5 mm deep and its plug adds as much again, but the fan leaves only 28.5 mm behind the faceplate. So the port sits at the right-hand end of the row, where the coupler runs straight back past the tray into the channel beside the fan, its plug 2 mm clear of the fan. It clips into the same socket as the keystone patch panels.

Variants

• 1u — the tray as described.
• 1u_labelled — 8 mm capitals engraved under the controls, sized and spaced like the labels on the other models, with a matching inlay body so the letters print in a second colour. The label sits centred between the screen and the rail slots, and label and controls together have equal margins above and below.

Both carry an auto/manual rocker switch, a fan-speed knob and a USB keystone port, in a row to the right of the window. The window sits as far left as the cover posts allow, which leaves one wide block on the right for them and the label.

What you need

• A Crystalfontz CFAF480128A0-039TN-A1-1 display module, 105.50 × 37.00 × 10.73 mm, SPI, 3.3 V logic, 30-pin ZIF. Any other module is five parameters away in the script.
• A Raspberry Pi Zero 2 W — the only Pi that fits; a 4 or a 5 is 56 mm across. Fit it headerless with soldered leads: an SPI display is six wires, and nothing can be plugged onto a 2×20 header in 13.3 mm.
• A KCD11-101 mini rocker, an EC11 rotary encoder with a 15 mm shaft and a low-profile knob, and a USB-A F/F keystone coupler with a short USB-A to micro-USB cable (straight plug no wider than 16 mm) for the front panel, two DS18B20 waterproof probes, a 12 V → 5 V buck module, a 2N3904 and three resistors.
• 4 × M3 × 10 countersunk self-tappers, 12 × M2.5 × 6, a 0.5 mm foam strip for the module clamps, and your rack’s own panel screws.

Printing

Two parts, no supports. The tray prints front face down, so the visible face is on the bed. The cover prints rear face down with its bosses and clamp ribs standing up. Standard process at 0.16 mm layers, as the tray’s standing walls are hex-vented; PETG, 0.4 mm standard-flow nozzle.

A dust filter for the KWS Rack v2, Ilan Kushnir’s heavy-duty 10-inch homelab rack. With a fan blowing out of the top of the rack, such as a HAVN H18 180 mm, the rack breathes in through its base. This plate makes all of that air come through a 50 mesh stainless screen.

It fits the rack as built. Every number comes from the rack’s own 6U base project, not a photo. The base legs and side bars form a ring with a clear 258.4 × 230 mm opening. The filter fills it with 0.4 mm to spare on every side, stands on eight feet on the looped base legs’ lower bars, and its face stops 0.2 mm below the top of the bars. U1 starts on top of the bars, so whatever you mount in the bottom U is unaffected. The fit was checked against the rack’s own meshes: nothing overlaps, and the feet land on both base legs.

How the mesh is held. Lay the mesh on the plate and screw the frame down on top. A 2 × 1 mm tongue round the frame’s underside presses the mesh’s border into a groove in the plate. That grips the border and pulls the mesh taut across the window. The groove keeps its full clamping depth, then closes underneath as a self-supporting 45° V instead of a flat bridge. The screws sit outside the mesh, so it is a plain rectangle with no holes to punch. Both parts carry the same hex grid of 34 mm across-flat cells, lined up rib on rib, so the mesh is supported from below and guarded from above without losing more airflow.

Air. Air reaches the underside of the rack through the gaps under the side bars and the slots through the base legs, about 12,800 mm² in all. A 50 mesh screen in 0.20 mm wire across the ~36,700 mm² of open grid passes about the same, so the filter does not become the bottleneck. Use the finest wire you can find.

Variants

• one_piece: the plate (257.6 × 229.2) and the frame, each in one piece. For the H2S / H2D.
• split_halves: the same parts cut down the middle for 256 mm beds (X1C, X1E, P1S, P1P, P2S, A1). The two halves of each part are identical, so print two of each. The rack’s bars hold the halves side by side and there is no joint to glue. Screws 12 mm either side of the cut keep the clamp tight at the frame halves’ ends (18 screws in all).

What you need

• 50 mesh stainless steel screen, one A4 sheet (297 × 210 mm). Cut the 297 mm side to 238 mm, keep the 210 mm side, and snip the corners off at 45°. Finer wire (0.20 mm) passes more air than 0.25 mm.
• 16 × M3 × 10 countersunk screws (ISO 10642 / DIN 7991) and 16 × M3 heat-set inserts, 5.7 mm long and 4.6 mm OD. Split halves: 18 of each.
• A KWS Rack v2 with its looped base legs. The rack’s own heavy-duty base (the slotted floor) can stay: the filter sits 0.2 mm under it. Not checked against the optional bottom stoppers.

Printing

No supports. The plate prints on the face the mesh sits on, with the grid and feet standing up. The frame prints on its visible face, with the tongue up. The groove’s hidden floor closes at 45°, reducing the void beneath its final closing bead to at most 0.6 mm instead of spanning the full 3.2 mm groove. 0.20 mm Standard, PETG, 0.4 mm standard-flow nozzle.

• One Piece on an H2S: plate 4 h 13 min / 138 g, frame 2 h 46 min / 91 g.
• Split Halves on an X1C: each plate half 2 h 24 min / 72 g, each frame half 1 h 34 min / 47 g (print each twice).

Assembly

1. Press the heat-set inserts into the plate, flush with the face the mesh sits on.
2. Lay the mesh on the plate and set the frame on top.
3. Start every screw, then tighten a little at a time, working from the middle of each side out to the corners. The tongue pulls the mesh taut as it goes down.
4. Drop the filter into the rack’s base, feet down, before filling U1. For split halves, place both plate halves in the base, lay the mesh across both, then screw on both frame halves.

To clean it: vacuum from above, or lift it out. Swap two diagonal screws for long M3 screws, thread them a few turns into their inserts, and lift by them. Take the frame off to wash the mesh.

Notes

• The plate stands on its front and rear feet, 230 mm apart. It holds itself, the mesh, cables and a power brick. It is not a shelf for a heavy device placed straight on the rack’s floor.

A drop-in tray for 10" mini racks (Project MINI RACK / DeskPi / GeeekPi style cabinets) that holds a UniFi Switch Ultra — the USW-Ultra and the USW-Ultra-210W share the same 203 × 76 × 33 mm chassis, so either fits. The switch sits by its base plate on a floor rim in a snug pocket, its feet hanging in the open floor. No screws — it lifts straight out. Two layouts:

• Window (1u_window): the switch’s front face sits against the back of the panel and the panel’s window is that face less a 3 mm bezel, so the seven PoE+ ports, the LED and the reset button are all there at the front of the rack, with the switch’s own port numbers under them, and the panel itself keeps the switch in place. 85 mm deep.
• Recessed (1u_recessed): the switch is set back 100 mm behind a solid faceplate with eight keystone sockets — ports 1–7 and the rear PoE++ / uplink port 8 — so every port comes to the front through keystone couplers and the switch is hidden. 185 mm deep. Fit a keystone blank in any slot you don’t patch.

The keystones click in properly. Every opening in the recessed faceplate has a socket behind it — a collar whose lips catch the module’s clips 8 mm behind its face, the same socket as the Mac mini bracket and the keystone panels, measured off widely printed patch panels and tested with a real coupler — so a module seats flush, clicks home, and comes out again by pressing its tab and tilting it forward. Each socket is shaped for the standing faceplate — a 45° wedge under the collar, one sloped roof over the clips — so it prints without supports and bridges only across the top of the opening and under the top lip, one layer each.

Four variants are included. There are four print profiles — the two layouts, each for the H2 series and for the X1 / P1 / A1 series — and in each profile both variants of that layout are named plates: open the profile for your layout and printer, pick the plate, slice. The STEP files carry the same names:

• 1u_window / 1u_window_labelled — the labelled one adds a label cover with “UNIFI USW-ULTRA” in white above the window.
• 1u_recessed / 1u_recessed_labelled — the labelled one adds a label cover with “UNIFI USW-ULTRA” below the keystones and a port label over every keystone: 1 to 7, and IN for port 8, all in white.

Within a profile the labelled plate comes first.

Why 100 mm? In 1U there is no room to loop a cable up over a coupler, so the plugs meet nose to nose: the keystone coupler is 26 mm deep, the plug in its back up to 33 mm with a boot, the plug in the switch another 33 mm — 92 mm, plus slack for the S-bend between the 21 mm keystone pitch and the switch’s 22.5 mm port pitch. Slim (boot-less) patch leads have 30 mm to spare, standard ones about 8 mm. The lead for port 8 runs forward from the rear of the switch over its top — there are 7 mm between the switch and the U above, enough for a slim patch cable.

Designed for the rack. 254 mm panel, holes on 236.5 mm centres, slots at every EIA position so you can fix it at any rail hole, 2 mm corner radii. 40 mm gussets and 4 mm walls carry the 320 g switch from the front rails. The tray is 213 mm wide (10" racks give ~220 mm between the rails); allow ~40 mm behind it for the rear plugs (port 8 and the DC barrel).

Open floor, vented everywhere else. The switch’s base plate sits on a 12 mm rim and the floor inside it is open (its feet hang in the opening); the recessed layout’s bay floor and both layouts’ outer side walls are vented with the pointy-top honeycomb — 7 mm holes on 2 mm ribs, 60 % open, the same vent as the Mac mini bracket.

Two-colour label cover (_labelled variants). The labels are not printed into the standing tray: they are on a separate 2 mm cover that fits over the whole faceplate and prints flat, face down, so the white letters are an inlay in its first five layers — crisp, with nothing standing or overhanging, and only five filament changes a plate. It slides down onto the panel from above: dovetail hooks down both sides run in grooves down the panel’s edges and hold its ends flat against the panel, screwed into the rack or not, and it rests on a rim along its top. It repeats the rail slots, so the rack screws pass through both. It opens out round the window, so the switch shows; on the keystone faceplate it is the sockets’ front skin, so every coupler sits flush with the cover’s face - fit the cover first, then clip the couplers in through it (and take them out before sliding it off). In the print profiles the cover sits on the same plate as the tray (on 256 mm plates the recessed one gets a plate of its own), its letters on filament 2 (white PETG) already — just pick the plate and slice. Single-colour printers: delete the cover’s text part before slicing and fill the 0.8 mm recesses with a paint pen (printed in one colour, the flush inlay would simply vanish).

What you need

• 10" mini rack at least ~125 mm deep behind the front rails for the window layout (85 mm tray + rear plugs), ~225 mm for the recessed one. Width is not critical: the tray is 213 mm wide.
• A UniFi Switch Ultra (USW-Ultra) or USW-Ultra-210W.
• 4× rack screws + cage nuts (M6, 12-24 or 10-32 all fit the 6.5 × 8.5 mm slots); with a label cover they pass through 6 mm of plastic under the head (the 2 mm cover and the 4 mm panel)
• For the recessed layout: up to eight RJ45 keystone couplers (Cat6/6A in-line couplers; PoE++ passes through a Cat6 coupler fine) and short patch leads from the switch’s ports to the back of the couplers — 15 cm slim leads are ideal, standard booted ones fit with a few millimetres to spare. Keystone blanks for empty slots are in the same repo.

Print settings (built into the profiles)

This is a cantilevered shelf from the front panel, in a cabinet that gets warm, so the profiles are set up for strength rather than speed:

• 5 walls on 0.5 mm lines — every load-bearing wall in the tray is 4 mm or thinner, so five 0.5 mm perimeters make the panel, gussets, uprights and vent ribs fully solid, with whole loops rather than gap fill.
• 40 % gyroid infill in what is left (the core of the 4 mm floor and panel).
• 6 top / 5 bottom layers, 0.16 mm layers (the standing side walls’ vent holes and the keystone sockets print cleaner in thinner layers), 0.4 mm standard-flow nozzle; seams on the rear so the front face is clean; no brim (256 mm plates only leave 1 mm); purge for the two-colour label flushed into infill.
• Material: PETG (Bambu PETG Basic, textured PEI plate at 70 °C). A PoE switch running 40 W of PoE in a closed cabinet warms the air around it, so avoid PLA; ASA or PETG-CF if your rack runs hot — swap the filament preset, the process settings stay the same.
• Orientation as exported: floor on the bed, front panel standing up. No supports. The panel stands, so the top edge of every opening in it is a bridge; the rail slots bridge on their own, while each keystone socket has six breakaway posts, and the window layout’s 197 mm window carries seven breakaway posts so no span is over 25 mm. Snap them out sideways before you fit the switch — they break at a narrowed neck on the sill and leave a sub-millimetre nub. The profiles already print bridges thick and slow (25 mm/s) for a clean top edge.
• Time and material on an H2S: plain window tray ~2.5 h / 79 g, labelled (cover included) ~3.2 h / 95 g; plain recessed tray ~6.7 h / 169 g, labelled ~7.6 h / 192 g. The white is only 2.6–2.8 g — five filament changes for the cover’s inlay, each with the full purge because the white letters are its visible face. X1 / P1 / A1 printers take longer.
• Footprint is 254 × 85 mm (254 × 185 recessed): comfortable on the H2S/H2D plate; on 256 mm plates (X1C, X1E, P1S, P1P, P2S, A1) it fits only axis-aligned with 1 mm to spare each side, so print without a brim — the print profile already places it (the recessed tray’s label cover on a plate of its own there). It does not fit the A1 mini.
• The lettering has its own slower settings built in (60 mm/s, Arachne walls), so the small white letters bond to the layer below instead of being dragged at full speed.

Assembly

On the recessed keystone faceplate, bend out the three breakaway posts beneath each socket’s front lintel and the three beneath its rear upper catch before fitting couplers. They shorten the 15 mm bridge to four 2.55 mm clear spans.

1. Window layout: snap the seven breakaway posts out of the window (push each sideways; it breaks at its neck) and trim the nubs on the sill flush if any stand proud.
2. Labelled: slide the cover down onto the front panel from above, its hooks in the grooves down the panel’s side edges, until it rests on its top rim. It only goes on and off that way, so fit it before the tray goes into the rack.
3. Fit the tray to the rails with cage nuts and screws (any of the slot positions); with a cover they go through both.
4. Recessed: push the keystone couplers into their sockets from behind, face first, until they click home flush with the faceplate (blanks in the ones you won’t use). To take one out, press its tab from behind, tilt its top forward to lift the bottom hook over the socket’s lower lip, and draw it back out.
5. Lower the switch into the pocket onto the floor rim — front face against the panel (window) or against the front lip (recessed), LED end to the left.
6. Recessed: plug a short lead into each port and into the back of its coupler; run the port 8 lead forward over the switch’s top to the IN coupler if you patch the uplink at the front.
7. Plug the power in at the back — the DC adapter, or PoE++ into port 8.

Six drives, pulled from the front. Each 3.5" drive rides in a printed sled with two pins that drop into the drive’s rear side holes, the pair every current NAS drive has. No screws. Slide the sled in and the drive’s own SATA plug meets a 22-pin male-to-female pass-through adapter at the back of the bay; ordinary SATA data and power cables plug into the adapter’s back and never move.

Why 4U. Standing on edge, a drive’s side holes face up and down, so the sled’s rails lie on its narrow edges and add nothing to its width. That gives six bays on a 35.5 mm pitch with 3.7 mm of air down each side of every drive. A mini-ITX board is 170 × 170 mm, though, and in a body that has to pass between a 10" rack’s legs it fits neither beside nor behind the drives. So the board gets a 1U deck of its own underneath.

Two ways to hold a drive in. Both sleds fit every bay:

• Snap latch. A ratchet: a pawl on an arm clicks over 1 mm teeth in the bay roof. Wherever the drive seats, it is held within a millimetre of fully mated, with nothing left bent or loaded. Press the tab above the bay, pull with a finger in the slot below it.
• Cam lever. Server style: a lever hooks a slot behind the panel. Closing it draws the drive onto its connector at about 5.6 : 1; opening it pushes the drive 12 mm off. A click detent holds it shut.

Power and cooling. Behind the drives, a fanless HDPLEX 250W GaN supply hangs under the cage’s roof, so the SATA power leads never leave the cage. Two 92 mm fans behind it, on the plate that closes the back of the cage, pull air in through each sled’s vented front plate, along the ducted bays and out of the rear of the rack.

Keystones. The deck comes plain, with a vented panel, or with eight keystone sockets across it for network, USB or HDMI couplers.

Built to be checked. The FreeCAD script asserts all of this on every rebuild:

• every part seated in every bay touches nothing, nor the PSU, the fans or the ears;
• every keystone module seats, tilts out to release, and has a lip behind each clip;
• the pins sit in their holes;
• the ratchet holds at every tooth across ±1.5 mm of tolerance;
• the released sled and the opened lever both slide out cleanly;
• the lever pushes the drive further off than the SATA guide posts engage.

Variants

• coupon — one bay of the cage with both sleds, the lever and an adapter carrier. Print this first.
• 3u_drive_cage — the cage, an adapter carrier (print 6), the fan plate and the rear ears.
• snap_latch_sled — print 6, or
• cam_lever_sled — the sled and its lever, print 6.
• 1u_compute_deck — the deck with a vented panel, or
• 1u_compute_deck_keystones — the deck with eight keystone sockets.

Everything prints on any Bambu printer except the Keystones deck (231 mm deep), which needs an H2-series plate (H2S / H2D). The cage just fits an X1 / P1 / A1, standing 248.5 mm tall.

What you need

• 6 × SATA 22-pin male-to-female pass-through adapters with two screw ears (about US$4 each). Measure one before printing the carriers.
• A mini-ITX NAS board with 6 SATA ports and 2 × M.2 (e.g. CWWK / Topton N150–N355), no taller than 31 mm over the PCB. Use right-angle SATA cables and a right-angle 24-pin adapter.
• An HDPLEX 250W GaN AIO ATX supply, a snap-in C14 inlet and a 16 mm momentary anti-vandal switch.
• 2 × 92 × 92 × 25 mm PWM fans.
• For the Keystones deck, up to 8 keystone couplers.
• Hardware:
  • 16 × M3 heat-set inserts;
  • M3 screws, nuts and washers;
  • for lever sleds, 6 × M3 × 16 with nyloc nuts.
• A four-post 10" rack: the rear ears bolt to the rear posts (made for the KWS Rack v2, 260 mm between mounting faces).

Print settings

0.20 mm, PETG, 0.4 mm standard-flow nozzle, 5 walls, 40 % gyroid, no supports.

• Cage: face down, about 23 h and 1.2 kg with its carrier, fan plate and ears on an H2S plate (on an X1 / P1 / A1, the plate and ears print separately).
• Deck: 6–7 h, 200–230 g.
• Sleds: 1.5–2 h and 70–80 g each.
• Coupon: about 8 h on two H2S plates.

Assembly

Before fitting couplers to the Keystones deck, bend out the three breakaway posts beneath each socket’s front lintel and the three beneath its rear upper catch. They print with the deck and snap at their narrow feet.

1. Heat-set the inserts. Screw the adapter carriers to the cage floor loosely, the adapters to them loosely, and plug in the SATA data leads.
2. Put the drives in their sleds: front end first, then spring the rails apart until the pins click into the rear side holes.
3. Latch a sled in each bay, push that bay’s adapter onto the drive’s plug from behind, and tighten it there.
4. Screw the PSU up under the cage’s roof and connect its leads. Fit the fans to the fan plate and slide the plate in from behind.
5. Build the deck, slide it into the rack, then the cage above it, and fit the rear ears.

Blank faceplates for 10" (254 mm) mini racks that fill the gaps a rack of odd-height gear leaves — any height in 1/4 U and 1/3 U steps (1/4 U, 1/3 U, 1/2 U, 2/3 U, 3/4 U, 1U, 1 1/4 U … 7 U; a 7 U panel is 310.65 mm, which fits an H2 series plate flat, up to 5 U fits a 256 mm plate) — with the rail holes right for wherever the panel sits, ventilation in five patterns (pointy-top honeycomb recommended), and a label of your own: text in capitals and any of 134 icons (server, NAS, Wi-Fi, ethernet, router, camera, Raspberry Pi, Docker, lightning, power, warning… and the logos of UniFi, TrueNAS, Unraid, Pi-hole, AdGuard, OPNsense, MikroTik, Jellyfin, Nextcloud, Immich, Portainer, Traefik, MQTT, ESPHome, Home Assistant, Proxmox, Nvidia, HP, Dell, GitLab, Tux, AWS…) engraved as a two-colour inlay. Hit Customize to set the height, where in the U grid the panel goes, the thickness (4 mm default), corner radius (2 mm), the vent pattern and the label, or download one of the stock panels.

Rail holes that fit. 6.5 × 8.5 mm slots at 236.5 mm centres at every EIA position the panel covers. A fractional panel’s holes depend on where in the U it sits, so the Customizer asks (offset_u: on a U line, or 1/4, 1/3, 1/2, 2/3 or 3/4 U above one). A hole that would land on the panel’s edge becomes a notch open to that edge; the neighbouring panel gets the matching notch and one screw and washer holds both. 1/3 U panels always get a full slot per side; 1/2 U panels one slot plus the mid-U notch; 1/4 U panels (10.6 mm) are always notched. An unlabelled panel can be flipped to swap its top and bottom holes.

Ventilation: hex — 7 mm pointy-top honeycomb with 2 mm ribs, the same vent as my trays, brackets and keystone panels and the recommended plain vented panel; cairo — Cairo pentagons with 7 mm holes on 2 mm ribs, round — 7 mm holes on a staggered grid, slot — 30 × 4 mm slots, square — 7 mm squares; whole cells only inside a 4 mm border, the 22 mm rail ears and the label kept solid.

Label: capitals in Overpass Mono Nerd Font Bold, 8 mm high by default (shrinks to fit), centred, left or right. Write {server}, {wifi}, {ethernet}, {lightning}, {unifi}, {truenas}… in the text for an icon — "{server} NAS {wifi}" — the full list of 134 is on the glyph sheet image (a few fine logos need 9–16 mm capitals, marked there; the model warns); | starts a new line ("{server} HOMELAB|10.0.0.0/24"), lines centred as a block and shrunk together to fit. The inlay is a separate body in the second colour; a single-colour printer prints the panel alone and fills the engraving with a paint pen. The Customizer needs no font: every glyph is built into the model.

38 stock panels in two print profiles per printer family: under 1U (1/4, 1/3, 1/2, 2/3, 3/4 U — 20 plates) and 1U to 2U (1U, 1.5U, 2U — 18 plates), each height solid and in the vent patterns that fit it (nothing fits in a 1/4 U panel, only a row of slots in 1/3 U, everything but Cairo in 1/2 U). Directory names spell out the panel: 1u_cairo_vented, 0.5u_slot_vented, 0.33u.

What you need

• A 10" rack with EIA-spaced rail holes (6.35 / 22.225 / 38.1 mm per U) and M5 or M6 screws; the 6.5 × 8.5 mm slots give 1 mm of play each way.
• Two filaments for a labelled panel (black PETG panel, white inlay in the profiles); one for a plain or vented panel.

Print settings (built into the profiles)

• Bambu 0.20 mm Standard with 5 walls, 40 % gyroid, 6 top / 5 bottom layers, seam at the rear, no brim, purge flushed into infill. PETG (Bambu PETG Basic, textured PEI plate); PLA is fine for a panel that carries nothing.
• Orientation as exported: flat, front face down, no supports — the front face gets the plate texture and the label inlay is the first four layers (one filament change). The Customizer’s preview therefore shows the rear of the panel; set print_face to up to look at the front (then flip it in the slicer, or print it face up and accept a top-layer finish on the front).
• Footprint 254 mm wide: fits the X1 / P1 / A1 plates (1 mm from each edge), the P2S and the H2 series; not the A1 mini.

Assembly

1. Hold the panel to the rails with a screw per side through each slot; notched holes share the screw with the panel next to them — fit both panels, then tighten.
2. Fractional panels: set offset_u to where the panel’s bottom edge sits in the U (the top of a 1U-plus-1/3 device sits at 1/3 U, so the 2/3 U panel above it is at offset_u = 1/3).

A 3U case for a mini-ITX PC with a full-length graphics card, built to go in a 10" rack and made as deep as the KWS Rack v2, ending flush with its rear posts. The rack is the case: the tray holds the board, the card, the supply, a power button and six keystone ports, and screws to the front and rear rails.

The board is on the floor. A graphics card lying flat will not fit beside a 170 mm board in a 211 mm-wide tray, so the two are stacked. The board screws to bosses in the floor over a grille, with its rear I/O at the foot of the rear wall, placed exactly where the microATX spec puts it, and 57 mm over it for the CPU cooler — all of the Mini-ITX spec’s zone.

The card lies over it in a drop-in cradle. The cradle is a printed frame: two beams under the card, rails along the walls, and a port tunnel that takes the card’s bracket and the screw through its tab. Mount the card on the bench, lower the cradle onto the ledges in the side walls, and plug in the riser. To work on the board, lift the cradle out with the card. The card lies fans up, under a grille in the lid, and its outputs leave through a window in the rear wall above the board’s I/O. Fans up with its bracket at the rear, its edge fingers sit right over the board’s PCIe slot, so the riser is a short ~100 mm one. Every card’s PCB sits at the same height, whatever its backplate: a card with a shallower one stands on the printed shims supplied.

The supply is an HDPLEX 500W GaN. 86.5 mm is all that is left in front of the board, and an SFX supply does not go in it. The 200 × 55 × 40 mm HDPLEX does, standing on the floor the right way up, its DC connectors opening upwards beside the card’s power plug.

The faceplate carries six keystone sockets and a 16 mm anti-vandal power button over the supply (USB from the board’s internal headers; RJ45 and HDMI looped in from the rear through a lead slot). At the rear: the ATX I/O aperture (the wall thinned to 1.2 mm for the shield’s clips), the card’s port window, a snap-in C14 inlet and separate rear ear plates for the rear posts.

Variants

• 3u — grilles only where the air has to pass: under the board, beside the board and the card, over the card’s fans and at the supply’s exhaust.
• 3u_vented — pointy-top honeycomb (nominal 7 mm holes, 2 mm ribs, 60 % open) across the faceplate, walls, floor and lid.
• 3u_labelled / 3u_vented_labelled — a 2 mm cover over the faceplate with an engraved label and a matching inlay for a second colour, printed face down. It is the keystone sockets’ front skin, so the couplers sit flush with its face: fit the cover first, then the couplers.

What fits

• Graphics card: up to 244 mm long in front of its bracket and 126 mm tall, with a dual-slot bracket — the RTX 4070 Super and 5070 Founders Edition and other two-slot cards get 15 mm or more over their fans; 2.5-slot cards fit with less. 500 W suits about an RTX 5070 with a 65–105 W CPU.
• CPU cooler: up to 57 mm; about 47 mm leaves a top-down cooler air under the card (Noctua NH-L9i / NH-L9a, Thermalright AXP90-X36 / X47, ID-Cooling IS-40X V3).
• Rack: 10" with a 222 mm opening between the legs and 260 mm to the rear posts’ rear face (KWS Rack v2). Measure yours.

What you need

HDPLEX 500W GaN AIO ATX supply, a snap-in C14 inlet for a 2 mm panel (and a 3-pin Mini-Fit Jr lead to reach it if HDPLEX’s does not), a ~100 mm PCIe 4.0 x16 riser whose ribbon leaves the back of its socket, a 16 mm momentary anti-vandal button, up to six keystone couplers, 4 × M3 heat-set inserts and M3 screws, and your rack’s screws.

Printing

No supports: the tray floor down (22–26 h on an H2S), the card’s cradle standing on its beams, the lid, the rear ear plates and the card’s shims flat, and on labelled variants the cover face down. The tray is 254 × 264 mm, so the profiles are for the H2S / H2D. PETG, 0.16 mm layers (the standing walls are hex-vented), 0.4 mm standard-flow nozzle. Snap the breakaway posts out of the port window, the I/O aperture, the cradle’s tunnel and both ceilings of every keystone socket before assembly.

A drop-in tray for 10" mini racks (Project MINI RACK / DeskPi / GeeekPi style cabinets) that holds a Mac mini M4 plus UGREEN 40Gbps M.2 NVMe SSD enclosure(s) and brings the ports to the front through keystone couplers. No screws hold the devices — the Mac mini stands on its own foot inside a vented pocket, and the enclosures sit in snug pockets — so everything lifts straight out.

Sixteen variants are included. There are four print profiles — 1.5U (one NVMe) and 2U (two NVMe), each for the H2 series and for the X1 / P1 / A1 series — and in each profile every variant of that layout is a named plate: open the profile for your layout and printer, pick the plate, slice. The STEP files carry the same names:

• Layout: 2u_dual_nvme_vertical — 2U, two NVMe enclosures standing on edge, 7 keystone slots (3× USB-C/Thunderbolt, RJ45, HDMI, 2× USB-C for the drives). 1.5u_single_nvme_flat — 1.5U, one enclosure lying flat, 6 keystone slots.
• _no_keystones — solid front panel with no cut-outs, for cabling straight to the Mac or drilling your own layout. With nothing to plug in behind the panel it keeps the shallower 26 mm cable bay, so the tray is 166 mm deep instead of 192 mm.
• _vented_panel — the front panel is a pointy-top honeycomb grille (the same 7 mm holes as the tray) with a solid border around the slots, the rail ears and the label. Best airflow, still stiff.
• _labelled — “MAC MINI M4 + 2 X NVME” / “MAC MINI M4 + NVME” in white on a cover plate that slides down over the panel and hooks onto its edges; the keystone row and the label sit together in the middle of the panel.

Any combination works, e.g. 2u_dual_nvme_vertical_no_keystones_vented_panel_labelled. Within a profile the plates run vented panel before solid, keystone before no-keystone, labelled before plain.

Designed for airflow. The M4 Mac mini breathes through a ring of slots round the sloped side of its foot: the rear of the ring blows the exhaust out and the rest draws air in. Its foot stands on a pad ring 3 mm above a floor vented with 7 mm pointy-top hexagons (cable bay included), so every slot is in open air, and a low baffle under the Mac sends the exhaust out through the vented rear guard, over a solid floor, instead of back into the intake or across the NVMe bay. The enclosure bay walls, the guards in front of and behind the enclosures and the outer side walls are vented too, so the fanless UGREEN cases get air across their fins front to back, and the floor under each enclosure slot is open — the case sits on a 4 mm lip around the opening. (On the 1.5U layout the front and rear guards both carry a rounded cable notch, so the enclosure can face either way; on the 2U layout the bay walls and guard stop below the on-edge enclosure’s port, so a plug clears them.)

Designed for the rack. 254 mm panel, holes on 236.5 mm centres, slots at every EIA position so you can fix it at any rail hole, 2 mm corner radii, and a 52 mm cable bay behind the panel so keystone bodies, the plugs behind them and their cable loops have room. The keystones click in properly: every opening has a socket behind it — a collar whose lips catch the module’s clips 8 mm behind its face, measured off widely printed patch panels and tested with a real coupler — so a module seats flush, clicks home, and comes out again by pressing its tab and tilting it forward. Each socket is shaped for the standing panel — a 45° wedge under the collar, one sloped roof over the clips — so it prints without supports and bridges only across the top of the opening and under the top lip, one layer each. Big triangular gussets and 4 mm walls carry the ~1.2 kg of hardware as a cantilever from the front rails.

Label (_labelled variants). The label is on its own 2 mm cover plate that goes over the front panel — the full width, with the rail slots and keystone windows repeated — and prints flat, face down, so the letters are an 0.8 mm inlay in its first layers: no overhangs anywhere, no supports, and the crisp first-layer finish on the face you actually look at. It slides down onto the panel from above: dovetail hooks down both sides run in grooves down the panel’s edges and hold its ends flat against the panel, screwed into the rack or not, and it rests on a rim along its top, so there is nothing to clip or glue. On keystone variants it is the sockets’ front skin, so every coupler sits flush with the cover’s face: fit the cover first, then clip the couplers in through it. Because only those five layers are two-colour, a labelled plate changes filament 4 times instead of 63 and uses about two and a half grams of white instead of sixteen. In the print profiles the frame and cover are filament 1 (black PETG) and the inlay filament 2 (white PETG). Single-colour printers get an 0.8 mm engraving to fill with a paint pen. Print your own text with the FreeCAD script.

What you need

• 10" mini rack with ~220 mm clear width between the rails — measure yours: the 2U tray is 217 mm wide and the 1.5U tray is 219 mm. If your rack is tighter, the FreeCAD script rebuilds it at any width.
• One or two UGREEN 40Gbps M.2 NVMe SSD Enclosures — the fanless model with the double-sided cooling fins, SKU 55316: https://www.ugreen.com/en-au/products/au-55316 (US: search “UGREEN 40Gbps M.2 NVMe SSD Enclosure”). The pockets are cut for its 122.0 × 66.2 × 27.2 mm body (1 mm clearance a side); UGREEN’s 40Gbps enclosure with a fan (CM642) is a different, smaller case and will not be held snugly.
• 4× rack screws + cage nuts (M6, 12-24 or 10-32 all fit the 6.5 × 8.5 mm slots)
• Keystone couplers for the ports you want on the front: USB-C, RJ45 (Cat6/6A), HDMI. USB-C keystone couplers are generally USB 3.x (10 Gbps) rather than Thunderbolt/USB4 — fine for peripherals and the NVMe enclosures at 10 Gbps, but keep the drive plugged straight into the Mac if you want the full 40 Gbps.
• Short patch cables from the Mac mini’s rear ports to the back of the keystones.

Print settings (built into the profiles)

This is a cantilevered shelf carrying ~1.2 kg from its front panel, in a cabinet that gets warm, so the profiles are set up for strength rather than speed:

• 5 walls — every load-bearing wall in the tray is 4 mm or thinner, so five 0.42 mm perimeters make the panel, gussets, uprights and vent ribs fully solid. Walls carry far more load per gram than infill (Bambu’s own Strength preset goes to 6 walls for the same reason).
• 40 % gyroid infill — all that is left for infill is the core of the 4 mm floor and panel; gyroid is equally strong in every direction under bending and shear.
• 6 top / 5 bottom layers, 0.16 mm layers, 0.5 mm wall lines, 0.4 mm standard-flow nozzle; seams on the rear so the front face is clean; no brim (256 mm plates only leave 1 mm); purge for the two-colour label flushed into infill.
• Thick bridges at 25 mm/s — the top edge of every keystone cut-out and rail slot is a short bridge through the standing panel; thick, slow bridging closes those edges cleanly with no supports.
• 0.16 mm layers, 0.5 mm wall lines, quiet cooling — every wall thickness here is a multiple of 0.5, so the vent ribs fill with whole perimeter loops instead of a thin gap-fill core, and the top of each hole in a standing wall (the pointy-top hexagons close at 60° over 7 mm) gets the overhang slowdown it needs, with the part fan never above 50 %. Finer than 0.16 mm is not worth chasing: a colour change purges a fixed volume, so the wipe tower grows as the layer thins until the two-colour plates no longer fit beside the tray.
• Material: PETG (Bambu PETG Basic, textured PEI plate at 70 °C). PETG holds up to ~65–75 °C under load; PLA starts creeping around 55–60 °C, which a closed cabinet with a Mac mini in it can reach, so avoid PLA. If your rack runs hot or sits in a hot room, print it in ASA (or PETG-CF / PET-CF): just swap the filament preset, the process settings stay the same.
• Orientation as exported: floor on the bed, front panel standing up. No supports — the vents, keystone slots and rail slots all print as vertical holes, the cover lies flat on its face, and the Mac mini ring is a simple step.
• Time and material on an H2S: 2U tray ~11.4 h / 300 g, 1.5U ~9.7 h / 248 g; a labelled plate prints the tray and its cover together — 12.8 h / 347 g + 2.8 g of white on the 2U, 10.9 h / 283 g + 2.8 g on the 1.5U — with only 4 colour changes, in the cover’s five inlay layers. On the 256 mm printers the cover takes a plate of its own. X1 / P1 / A1 printers take longer.
• Footprint is 254 × 192 mm (254 × 166 mm without keystones): comfortable on the H2S/H2D plate; on 256 mm plates (X1C, X1E, P1S, P1P, P2S, A1) it fits only axis-aligned with 1 mm to spare each side, so print without a brim — the print profile already places it clear of the X1/P1 front-left exclusion corner. It does not fit the A1 mini.
• Vented-panel variants print the panel vent as vertical holes too — no change in settings.
• Labelled variants add the cover plate, flat and face down, with its label inlay in the first five layers; the profiles flush the purge into infill so the prime tower stays small.
• The lettering has its own slower settings built in (60 mm/s, Arachne walls), so the small white letters bond to the layer below instead of being dragged at full speed.

Assembly

Before fitting couplers, bend out the three breakaway posts beneath each socket’s front lintel and the three beneath its rear upper catch. They shorten the 15 mm bridge to four 2.55 mm clear spans and snap at their narrow feet.

1. Labelled: slide the cover down onto the front panel from above, its hooks in the grooves down the panel’s side edges, until it rests on its top rim. It only goes on and off that way, so fit it before the bracket goes into the rack.
2. Fit the bracket to the rails with cage nuts and screws (any of the slot positions).
3. Push the keystone couplers into the front panel from behind.
4. Drop the Mac mini in with its ports facing the rear — its foot stands on the pad ring, inside the pocket’s lips.
5. Slide the NVMe enclosure(s) into the pockets — the port can face forward or back, both guards are notched (1.5U) or low enough to clear the plug (2U).
6. Run short cables from the Mac’s rear ports forward to the keystones.

A drop-in tray for 10" mini racks (Project MINI RACK / DeskPi / GeeekPi style cabinets) that holds a Minisforum MS-A2 — the MS-01 and MS-A1 share the same chassis (189 mm wide across the front, 196 mm deep, 48 mm tall), so they fit too. The machine sits by its base plate on a floor rim in a snug pocket, its feet hanging in the open floor. No screws, feet on or off — it lifts straight out. Two families:

• Window (2u, 1.5u): the machine’s front face sits against the back of the panel and the panel’s window is that face less a 3 mm bezel, so the power button, three USB-A ports, audio jack and front vents are all there at the front of the rack, and the panel itself keeps the machine in place.
• Recessed (2u_recessed, 1.5u_recessed): the machine is set back 59 mm behind a solid faceplate and its ports come to the front through keystone couplers — every port you want, front or rear — with a Ø22 mm finger hole over the power button and a flanged slip-in plug, flush in a countersink, to fill it when you would rather have a clean plate (its handle is a bar flush with the plate across a bowl, its flanks leaning in so your fingers hook under it: pinch and pull). A low lip in front of the machine holds it. The power button sits 63 mm behind the faceplate: a slim finger reaches it, otherwise use a pen, BIOS auto power-on or a _no_power_hole variant.

Twenty-two variants are included. There are six print profiles — the four layouts for the H2 series, plus the two window layouts for the X1 / P1 / A1 series (the recessed trays are too deep for a 256 mm plate) — and in each profile every variant of that layout is a named plate: open the profile for your layout and printer, pick the plate, slice. The STEP files carry the same names:

• 2u — 2U window, with a row of 7 keystone sockets above the machine (2× RJ45 for the 2.5GbE ports, HDMI, 2× USB-C, 2× USB-A) so the rear ports can be patched from the front. The keystone bodies sit in the free space above the machine and the cables run back over its top cover.
• 1.5u — 1.5U window, compact: a 48 mm machine leaves only 14 mm of panel above it, so there is no keystone row; everything at the rear is patched at the rear.
• 2u_recessed — 2U, solid faceplate, two keystone rows: 7 slots for the rear ports over 4 slots for the front ports (3× USB-A, 3.5 mm audio). The rows sit above the port height so the plugs in the machine’s front ports and the coupler bodies never share space; the cables loop up in the 59 mm bay.
• 1.5u_recessed — 1.5U, solid faceplate, one row of 7 (the four front ports plus RJ45 / HDMI from the rear).
• _no_power_hole (recessed layouts) — an unbroken faceplate: no finger hole over the power button and no plug. For a machine you leave on, or wake with BIOS auto power-on / wake-on-LAN.
• _no_keystones (all but 1.5u) — no cut-outs: a solid band above the machine, or a blank faceplate with just the power-button hole (or nothing at all, combined with _no_power_hole) — for all-rear cabling or drilling your own layout.
• _labelled — “MINISFORUM MS-A2” in white on a 2 mm black cover that fits over the whole front panel, printed flat and face down so the letters are a crisp two-colour inlay. With keystones the label sits below the rows.

SFP+ DACs, the DC lead and the exhaust stay at the back in every layout.

Within a profile the plates run keystones before none, power hole before none, labelled before plain.

Designed for airflow. The MS-A2 draws its air in through the perforated base and exhausts through the top rear patch and the rear grille, so the tray floor is open under the whole intake: a 161 × 167 mm hole inside a 15 mm rim that the machine’s base plate sits on. The outer side walls carry a 7 mm pointy-top honeycomb vent, and on the recessed layouts so does the bay floor in front of the machine. Leave the U above the machine open or vented (another of these trays counts — its floor is open).

Keystones that actually latch. A keystone module is held by clips 8 mm behind its face, so a plain hole in a 4 mm panel holds nothing. Every opening has a socket behind it — a collar whose lips catch the module’s clips, measured off widely printed patch panels and tested with a real coupler — so a module seats flush, clicks home, and comes out again by pressing its tab and tilting it forward. Each socket is shaped for the standing panel — a 45° wedge under the collar, one sloped roof over the clips — so it prints without supports and bridges only across the top of the opening and under the top lip, one layer each.

Designed for the rack. 254 mm panel, rail slots on 236.5 mm centres, 2 mm corner radii. The 2U version has six short slots per side. The 1.5U version has three longer slots per side, repeated in its label cover, that fit both whole-U and half-U starting positions: two identical 1.5U trays stack in 3U. The nominal panel gap is 0.5 mm; the slots also fit when the upper tray rests directly on the lower one. 70 mm gussets and 4 mm walls carry the 1.4 kg machine as a cantilever from the front rails. The tray is 199 mm wide (10" racks give ~220 mm between the rails) and 205 mm deep. The recessed trays are 264 mm deep — the most a KWS Rack v2 takes: they pass between its rear posts and end flush with their rear face (measure a shallower rack first). Allow ~45 mm behind the machine’s rear face for the rear plugs in any layout.

Two-colour label cover (_labelled variants). The label is not printed into the standing tray. It is on a separate 2 mm cover that fits over the whole faceplate and prints flat, face down, so the white letters are an inlay in its first five layers: crisp, with nothing standing or overhanging, and only a handful of filament changes a plate. It slides down onto the panel from above: dovetail hooks down both sides run in grooves down the panel’s edges and hold its ends flat against the panel, screwed into the rack or not, and it rests on a rim along its top. It repeats the rail slots, so the rack screws pass through both. It opens out round the window and the power-button hole, so the machine shows and the plug fits exactly as without it; on labelled variants the plug’s rim is 2 mm taller, flush with the cover. Over the keystones it is the sockets’ front skin, so every coupler sits flush with the cover’s face too: fit the cover first, then clip the couplers in through it. With keystones the label sits below the rows (centred with them on 2U recessed, between the window and the sockets on the 2U window). In the print profiles the cover shares the tray’s plate on the window layouts and has a plate of its own on the recessed ones and on 256 mm plates. Its letters are already on filament 2 (white PETG), so just pick the plate and slice. Single-colour printers: delete the cover’s text part before slicing and fill the 0.8 mm recesses with a paint pen (printed in one colour, the flush inlay would simply vanish).

What you need

• 10" mini rack at least ~250 mm deep behind the front rails (205 mm tray + rear plugs; ~295 mm for the recessed layouts). Width is not critical: the tray is 199 mm wide.
• A Minisforum MS-A2, MS-01 or MS-A1 (189 mm wide, 196 mm deep, 48 mm tall — the spec’s 196 × 189 × 48 is depth first), feet on or off.
• 4× rack screws + cage nuts (M6, 12-24 or 10-32 all fit the 6.5 mm-wide slots); with a label cover they pass through 6 mm of plastic under the head
• For the keystone layouts: keystone couplers for the ports you want on the front — RJ45 (Cat6/6A), HDMI, USB-C, USB-A, 3.5 mm audio — and short patch cables from the machine’s ports to the back of the keystones (from the rear ports, over the top cover; on the recessed layouts also from the front ports, looping up inside the bay — 15 to 20 cm leads are about right). USB-C keystone couplers are generally USB 3.x (10 Gbps), which matches the MS-A2’s rear USB-C ports; HDMI couplers are usually rated for 4K60 — use the rear port directly for 8K.

Print settings (built into the profiles)

This is a cantilevered shelf carrying a 1.4 kg machine from its front panel, in a cabinet that gets warm, so the profiles are set up for strength rather than speed:

• 5 walls — every load-bearing wall in the tray is 4 mm or thinner, so five 0.5 mm perimeters make the panel, gussets, uprights and vent ribs fully solid.
• 40 % gyroid infill in what is left (the core of the 4 mm floor and panel).
• 6 top / 5 bottom layers, 0.16 mm layers, 0.4 mm nozzle; seams on the rear so the front face is clean; no brim (256 mm plates only leave 1 mm); purge for the two-colour label flushed into infill.
• Material: PETG (Bambu PETG Basic, textured PEI plate at 70 °C). PLA creeps at the temperatures a closed cabinet with a 100 W machine in it can reach, so avoid it; ASA or PETG-CF if your rack runs hot — swap the filament preset, the process settings stay the same.
• Orientation as exported: floor on the bed, front panel standing up. No supports — the vents, window, keystone slots and rail slots all print as through-holes (each pointy-top hex roof in a standing side wall is a supported 60° overhang, helped by the 0.16 mm layers and overhang slowdown; each keystone socket sits on a 45° wedge, with one sloped roof over its clips), and the recessed layouts’ power-hole plug is shaped (a bowl that widens upward, a flange on a 45° chamfer) to print face-up without any. The one long opening — the machine window on the window layouts — has thin breakaway posts printed in it: 44 posts leave only 2.50 mm clear spans, matching the keystone support rule. Bend them sideways with pliers before assembly and they snap at a narrow neck on the sill, leaving a sub-millimetre nub on the window’s bottom edge.
• Time and material on an H2S: plain 2U tray ~7.3 h / 190 g, plain 1.5U ~5.5 h / 151 g; the recessed trays are longer with a solid faceplate: plain 2U recessed ~8.3 h / 241 g, plain 1.5U recessed ~7.1 h / 206 g. A label adds its cover: about 1.2 h and 32 g on the 2U window plate (0.9 h / 23 g on 1.5U), where it prints beside the tray; on the recessed layouts it has a plate of its own, ~1.5 h / 48 g (2U) or 1.2 h / 38 g (1.5U). About 2.8 g of that is white. X1 / P1 / A1 printers take longer.
• Footprint is 254 × 205 mm (254 × 264 recessed): comfortable on the H2S/H2D plate. On 256 mm plates (X1C, X1E, P1S, P1P, P2S, A1) the window trays fit only axis-aligned with 1 mm to spare each side, so print without a brim — the print profile already places them clear of the X1/P1 front-left exclusion corner. The recessed trays cannot clear that corner on a 256 mm plate, so they have H2 profiles only. Nothing fits the A1 mini.
• The lettering has its own slower settings built in (60 mm/s, Arachne walls), so the small white letters bond to the layer below instead of being dragged at full speed.

Assembly

Before fitting couplers, bend out the three breakaway posts beneath each keystone socket’s front lintel and the three beneath its rear upper catch. They shorten the 15 mm bridge to four 2.55 mm clear spans. Window variants have 44 removable posts across the machine opening, leaving 2.50 mm clear spans.

The power-button hole has five similar breakaway posts, with 2.33 mm clear spans and a 0.32 mm gap beneath its curved ceiling and countersink. Bend them sideways and trim any remaining foot flush inside the rear bore before inserting the plug. The feet stay off the countersink so its seating face remains clean.

1. Window layouts: snap the breakaway posts out of the window — bend each sideways with pliers, it parts at the neck on the sill.
2. Labelled: slide the cover down onto the front panel from above, its hooks in the grooves down the panel’s side edges, until it rests on its top rim. It only goes on and off that way, so fit it before the bracket goes into the rack, and before the power-button plug. Then fit the bracket to the rails with cage nuts and screws through the cover. On 1.5U trays, use at least the top and bottom slot on each side; the longer slots align with the rack both below and above another 1.5U tray. Tighten the screws to the rails.
3. Push the keystone couplers into the sockets from behind until they click home (to take one out, press its tab and tilt it forward).
4. Lower the machine into the pocket onto the floor rim — front face against the panel (window layouts) or against the front lip (recessed layouts). Recessed, where the faceplate has the hole: seat the plug in if you want the plate closed; pinch its bar and pull to reach the button.
5. Run short cables from the rear ports forward over the top cover to the keystones — keep them to the sides of the top vent patch. On the recessed layouts plug the front-port leads in and loop them up into the lower row.
6. Plug the SFP+ DACs and the power lead in at the back.

Patch panels for 10" mini racks (Project MINI RACK / DeskPi / GeeekPi style cabinets) that take standard keystone modules — RJ45 couplers or punch-down jacks, USB, HDMI, fibre, blanks — in 1U (one row) or 2U (two rows), with 4, 6, 8 or 10 cut-outs per row.

Modules that latch. A keystone module sits flush in its opening and is held by clips well behind the panel face — a sprung tab on top and a fixed hook underneath, about 8 mm back — so a flat printed plate has nothing for them to grab. Every opening here has a socket on the rear: a 2 mm-walled collar with lips turned in at its far end, 8 mm behind the front face, exactly where the clips catch, and a 2 mm skin around the opening so a module can be tilted out again. Push a module in and it clicks home flush; press the tab and tilt to release it, as in a metal panel. The socket geometry is measured off a published, widely printed 10" keystone panel.

Fifty-three variants are included. Eight layouts:

• 1u_4_port, 1u_6_port, 1u_8_port, 1u_10_port — one row, centred.
• 2u_8_port, 2u_12_port, 2u_16_port, 2u_20_port — two rows of 4 / 6 / 8 / 10, one per U.

And four options (numbers and label tiles exclude each other):

• _numbered — port numbers engraved above every cut-out (1…N, the second row continuing) as a two-colour inlay: the panel is on filament 1 and the digits on filament 2 in the print profiles already. Single-colour printers can print the panel alone and fill the engraving with a paint pen.
• _numbered_outside (2U) — the bottom row’s numbers under its cut-outs and the top row’s above, so the labels sit outside both rows and the band between the rows is clear (on vented panels the rows sit 3.5 mm further apart each way, for two rows of hex vent holes in that band).
• _label_tiles — instead of numbers, a recess and a magnet pocket next to every port for a printed label tile that holds magnet to magnet and swaps in a second. Type a port name into the tile customizer, add one of 118 marks if you like — Wi-Fi, server, NAS, access point, camera, printer, Home Assistant, lightning for PoE… and the logos of UniFi, Pi-hole, TrueNAS, Unraid, Jellyfin, Nextcloud and other homelab staples, the same set as the faceplates — print the tile face-down (first-layer text, two colours or paint-filled), drop a Ø6 × 2 mm magnet into it and one into the panel, done. Print the tiles with a 0.2 mm nozzle if you have one — the lettering is 4.5 mm high, and a 0.2 mm nozzle turns the strokes from under two lines into three or four, for noticeably cleaner text and icons on an 18 × 8 mm print that takes minutes either way. Keep names to four characters, or three beside an icon. Tiles sit above the ports on 1U and outside both rows on 2U (on vented 2U panels the rows sit 1.2 mm further apart, for two rows of hex vent holes between them).
• _vented_panel — the panel outside the keystone rows is pointy-top honeycomb (nominal 7 mm holes, 2 mm ribs), the same vent as the Mac mini bracket and the trays, with a solid border around the edge, the rail ears, the rows and the numbers. Most useful on the 2U panels and the 4- and 6-port 1U ones, which have the most blank panel to open up (the 1U 10-port has no room for it, so it comes solid only).

e.g. 2u_16_port_vented_panel_numbered. In each print profile every variant of that height is a named plate: open the profile for your height and printer, pick the plate, slice. Plates run by port count, then vented before solid, numbered (above, then outside), then label tiles, then plain.

Designed for the rack. 254 mm panel, holes on 236.5 mm centres, slots at every EIA position so you can fix it at any rail hole, 2 mm corner radii, 0.5 mm under the U height so it never fouls its neighbours. On the 1U label-tile panels the ports and their tiles are centred on the panel as a group, so nothing looks top-heavy. Cut-outs are 15.0 × 16.3 mm — the standard 14.5 × 16 mm module plus print clearance — on a 21 mm pitch — the same spacing as the keystone rows on my Mac mini, Blackview MP80 and MS-A2 trays, so panels and trays line up.

What you need

• A 10" mini rack with EIA-spaced rail holes.
• 4× rack screws + cage nuts (M6, 12-24 or 10-32 all fit the 6.5 × 8.5 mm slots).
• Keystone modules for the ports you want: RJ45 couplers (Cat6/6A; the in-line coupler type is ~30 mm deep behind the panel), punch-down jacks, USB, HDMI, fibre or blank inserts.
• The cut-outs are 0.5 / 0.3 mm larger than the nominal 14.5 × 16 mm module so printed shrinkage doesn’t make them tight, and the socket’s lips sit 8 mm behind the front face, where keystone clips catch. If a module of yours catches somewhere else, the FreeCAD script moves the lips (KS_CATCH_D) and rebuilds the panel.
• For the _label_tiles variants: two Ø6 × 2 mm neodymium disc magnets per port (one in the panel, one in each tile) and a drop of CA glue. The pockets are 6.2 mm; ream lightly if a magnet won’t push in, and push each panel magnet all the way home. Glue the panel magnets first, then sit each tile’s magnet on its panel magnet before gluing it into the tile, so the polarities come out right by themselves.

Print settings (built into the profiles)

• 5 walls, so the 4 mm panel and the 2 mm socket walls print solid; 40 % gyroid for whatever is left; 6 top / 5 bottom layers, 0.20 mm layers, 0.4 mm nozzle; seams at the rear; no brim; purge flushed into infill.
• Material: PETG (Bambu PETG Basic, textured PEI plate) to match the trays; PLA is fine for a panel that carries no load, ASA or PETG-CF if your rack runs hot.
• Orientation as exported: flat, front face down — the front takes the plate texture, the cut-outs and vent print as vertical holes, each socket lip sits on a 45° chamfer with a 1 mm flat catch face, and a label recess’s floor sits 1 mm behind its tile, where the bridge over it cannot reach the tile. No supports.
• Numbered variants change filament for the first four layers only (the 0.8 mm inlay), then print in one colour.
• Label tiles: 0.2 mm nozzle for the cleanest marks (see above); with a 0.4 mm nozzle they print fine but the marks tagged “fine” in the customizer’s dropdown (most logos, USB, LAN, HDD, antenna, @, %…) are better paint-filled than inlaid.
• Footprint: 254 × 44 mm (1U) or 254 × 88 mm (2U) — fits the 256 mm plates lengthways with 1 mm to spare, clear of the X1/P1 exclusion corner, and the H2 plates easily. Neither fits the A1 mini.
• The white marks have their own slower settings built in (60 mm/s walls, 40 mm/s gap fill), so small letters bond to the layer below instead of being dragged at full speed.

Assembly

1. Push the keystone modules straight into the cut-outs from the front until the tab clicks over the lip at the back of the socket. To remove one, press the tab from behind and tilt the module top-forward — that lifts its hook off the lower lip — then draw it out.
2. Fit the panel to the rails with cage nuts and screws (any of the slot positions).
3. Patch your cables from behind.

A rear bracket for the BLUEQUE 18-in-1 power board: 12 AC outlets (6 on its face, 3 two-pin on each side), 3 USB-A, 3 USB-C and an overload switch (Amazon AU B0DNFBMXN8). It screws to the rear posts of a four-post 10-inch rack like a front panel and becomes that stretch of the rack’s back wall. The board stands upright against it with its outlets facing into the rack, so every device’s power lead stays inside, and its switch and cord at the bottom.

Nothing covers an outlet. The board is held only by its two plain edges and the 3.5 mm rim step round its raised face panel. A fixed cradle along the bottom edge carries it: a floor, a cup round each bottom corner that locates it sideways, and a lip in the rim step, flush with the raised panel so a big plug body can overhang the panel’s edge. At the top, a snap hook in the rim step stops it tipping out. The hook rides on a stiff arm carried by a tongue cut out of the plate, so the part that flexes prints flat on the bed and bends along its layers. The board clicks in and lifts out without tools.

Room for big plugs on the sides. The board stands 12 mm clear of the plate on a ring hidden behind it, so a plug body in a side outlet can reach back past the board’s base. Nothing stands beyond the board’s side walls, and each side outlet has 39.8 mm to the KWS Rack v2’s rear posts: a two-pin plug body longer than that will not fit a side outlet.

Measured, not guessed. The board was measured with callipers (142.3 × 152.2 mm at its base, 33.53 mm deep, 2.5° drafted walls, R13 corners, a raised face panel 3.5 mm in and 2 mm proud), and the build checks the bracket against it: no overlap with the board, its cord or the space its plugs need; the board held when pushed forwards, sideways or up; and the board swung in on its bottom rim along the whole fitting path, with the hook lifting clear at every angle.

Variants

Frame height × the plate sealed or vented. The board, cradle, standoff and snap are the same in all four.

• 5u (221.75 mm tall): the fifth U is under the board, where the cord hangs on its boot and bends out the back through a 16 mm slot in the frame’s bottom edge, open at the edge so the plug never has to be threaded through.
• 4u (177.3 mm tall): for the bottom of a rack. The cord drops straight out of the cradle; its boot hangs about 10 mm below the frame, so the rack needs an opening in its floor under it.
• Sealed (no suffix): no openings but the rail slots, the cord slot and the slot round the snap tongue.
• _vented: the plate carries pointy-top hex vents (nominal 7 mm holes on 2 mm ribs) between the rail ears, kept solid under the standoff ring and round the cradle, the tongue and the cord slot.

What still fits in front of it

Only the board and its hook reach into the rack. On a KWS Rack v2 (260 mm from front to rear mounting face) that leaves 214.5 mm behind the front rails alongside the board and 206.5 mm at the hook’s tab, but a plug in a face outlet wants another 40–60 mm in front of the board, so in those rows plan on 155–175 mm. Rows the bracket does not occupy keep the rack’s full depth.

What you need

• A BLUEQUE 18-in-1 power board. The bracket is sized to that board only.
• A four-post 10-inch rack whose rear posts carry rail holes (EIA spacing, 236.5 mm centres), with the rear opening clear between the posts at the bracket’s rows. Designed and checked against the KWS Rack v2.
• M5 screws into the rear posts, as for a front panel: two a side is plenty.

Print settings (built into the profiles)

• Plate-down, no supports, 57.5 mm tall. The only overhangs are the lip’s and the hook’s catch faces, each over a 45° fillet.
• PETG, 0.20 mm Standard, on a textured PEI plate, 0.4 mm standard-flow nozzle.
• X1C: 4U 5 h 58 min / 209 g, 4U vented 7 h 07 min / 182 g, 5U 7 h 03 min / 246 g, 5U vented 8 h 32 min / 210 g. H2S: 5 h 39 min, 7 h 03 min, 6 h 41 min and 8 h 30 min.

Fitting and removing the board

1. Screw the frame to the rear posts. It can be done with the board already in.
2. Lean the board’s top towards you, drop its cord through the cradle’s slot and slide its base down the standoff ring until the bottom rim sits behind the cradle’s lip. On the 5U, bend the cord back and slip it up into the slot from below; on the 4U it hangs straight down.
3. Push the top back: the board’s top edge rides up the hook’s 45° lead-in and the hook clicks over the rim.
4. To take it out, lift the hook by its tab a couple of millimetres, pull the board’s top towards you and lift it out of the cradle.

An open-bottom stand for a NEEWER NL-116AI LED panel, lying diffuser-down over the Bambu H2S top glass. It keeps the 10 W light off the glass, lets heat rise around its open control face, and blocks the direct light path at all four edges so the useful light goes into the chamber rather than across the room.

• 18 mm diffuser standoff, with no floor under the light.
• 0°, 5° and 10° aim: the frame stays flat; the front rests on two pointed pivot ledges and the same pair of support pegs moves between three 4 mm-deep blind pocket pairs, each peg keyed to its teardrop pocket so it cannot lift or tip out. The 5.5 mm side walls leave at least 1.5 mm of solid material behind every pocket. At 10° the beam centre moves roughly 70–105 mm rearward over a 400–600 mm drop into the chamber. The keyed pegs remain removable by a straight inward pull.
• The side walls flare 11 mm outward at the glass and the rear wall flares 4 mm, opening the light well below the panel without moving its front edge into the automatic-vent keep-out. A continuous outer shell has R5 front and R6 rear corners and a low sloping rim. It remains 7 mm above the diffuser at the steepest setting, retaining the panel and blocking side spill without raised wings. Each vent floor shares the shell’s exterior surface, with no projecting floor edge or separate corner pieces.
• 5.5 mm side baffles, with four pointed inlets per side following the raised diffuser envelope and venting the cavity at its ceiling into 7 mm-deep outboard chimneys. Their solid outer walls block every inlet, so air turns upward before leaving and horizontal light cannot. Each chimney blends into the frame over 14 mm at the front, remains full depth across all inlets, then rounds directly into the rear wall.
• Control face open, charging edge accessible, light lifts straight out.

The flat light has 0.4 mm clearance at each end (0.8 mm total). The hidden inner face of the front wall follows the 10° swept light envelope, retaining all three settings without leaving that travel as a gap in the flat position.

The footprint is 240.2 × 138.8 mm. The reference assembly fits it in the measured 160 mm clear bay between the H2S lid-handle / automatic-vent zone and a rear AMS 2 Pro, leaving about 12.6 mm at the front and 8.6 mm behind the rear flare. Its fit check reserves the whole area ahead of the bay rather than guessing the handle’s detailed geometry. Watch the vent complete a full cycle before use. Nothing may rest on the handle or moving vent.

The updated pegs have Ø8.0 mm pocket ends, removing the former 0.2 mm diametral play in the existing pockets, with a 0.3 mm lead-in chamfer. Their exposed Ø7.8 mm seats keep the same light position. If you already have the holder, reprint only the two pegs. Check the printed fit before loading the light; the tighter fit is CAD-verified and awaits a physical fit test.

Print the holder flat and the two pegs upright in PETG, 0.16 mm layers, no supports, 0.4 mm standard-flow nozzle. The shallowest flared wall is 61.7° from horizontal, the pivot ledges and pocket pads are buttressed at 60° down to the wall or bed, the horizontal blind pockets use 45° teardrop roofs and the light-trap inlets use 60° pointed roofs. Four small heat-resistant silicone bumpons under the frame’s corners protect the glass and stop it walking; fit them only after establishing the correct position.

Summary

A printed, width/height/angle-adjustable overhead gantry for a Sony ZV-E10 II, SELP16502 16–50 mm lens, SmallRig 4867 / 4867-CF cage and 5328 Hybrid Cooling Fan. A keyed saddle accepts the SmallRig DBC2280 Arca-type clamp; the cage’s integrated Arca-Swiss base provides fast camera removal. One layout uses the clear top-glass strip in front of an H2-series printer’s rear AMS 2 Pro; a second, no-AMS layout points straight down at the bed centre.

Description

Two padded, braced towers carry a split channel beam without touching the AMS or the automatic front vent. Sliding post sockets fit 320–400 mm tower spacing. The AMS set has 230 / 250 mm telescoping positions, 15° / 20° positive settings and a 230 mm, 20° / 17.25 mm checked default. The taller no-AMS set has fully braced 245 mm lower towers, 300 / 320 mm positions, adds 0°, and uses 320 mm, 0° / 16 mm by default. Both use a 380 mm checked span.

The AMS towers sit toward the rear of 150 mm feet that leave 5 mm at both ends of the measured glass strip; the no-AMS towers use deeper 200 mm feet. A mandatory Ø12 × 440 mm M12 steel rod passes through support-free rear diamond bores as a low counterweight and lateral brace, balancing the forward camera while the wide field covers most of the bed. The beam is a 50 × 48 mm six-wall channel, the upper posts are closed 30 × 28 mm tubes with 6 mm walls, each post uses two height locks, and both sides of the camera cradle use positive angle locks. Four Ø4.5 mm foot holes accept optional low-profile M4-stud suction cups. Two low gantry tether points go to fixed anchors, separate from the camera-to-saddle tether.

Each offset upright terminates in a separate sliding socket. Its 8 mm top flange reaches beneath both bottom rails of the horizontal wing; two vertical M5 × 80 bolts clamp those rails and a horizontal M5 × 50 cross-bolt pins the socket to the upper post. Both rail contacts and all four vertical bolt paths are checked numerically in the source. The hanger is fixed through both beam rails at ten M5 stations, with its two outer stations directly over the boxed camera arms; each saddle ear is captured between paired cheeks so the pivot and detent bolts work in double shear.

The saddle keys the DBC2280’s approximately 50 mm square body in a 2 mm-deep pocket over a 1 mm silicone/TPU damping layer, reserves the full published 68 mm width through a one-sided knob relief, and provides a 42 mm mounting slot for its underside 1/4-20 threads. Measure the real clamp body before printing because SmallRig does not dimension that sub-feature separately. The cage’s integrated Arca-Swiss base goes directly into the clamp, so the DBC2280’s loose camera plate is not used. The asymmetric yoke clears the SmallRig 4867’s complete published 150 × 85.7 × 57.3 mm envelope plus ±5 mm lateral uncertainty, the LCD fully open, the published 85 × 50.8 × 32.8 mm cooler envelope and a 10 mm fan-face airflow keep-out at every allowed angle. Published clamp, cage, camera and lens envelopes, the H2S top-glass layout, the front vent/handle sweep and AMS footprint are explicit non-exported check bodies in the FreeCAD source. Every printed component fits a 256 mm plate and has a support-free export orientation. The 5328 cooler, DBC2280 kit and normal M4/M5/M6/M12/1/4-20 hardware are required and are not printed.

The source conservatively reports 0.427 g forward / 0.713 g rearward / 1.572 g sideways free-tip thresholds before suction or tethers for the AMS set, 0.058 mm gravity sag at the 400 mm beam span, and 0.016 mm estimated post motion under a 0.30 g horizontal shock at its 230 mm default. The taller no-AMS set reports 0.379 / 0.698 / 1.118 g and 0.029 mm post motion at its 320 mm default. A 312,868-node CalculiX check of the longer AMS hanger gives 0.0376 mm lateral camera-head motion at 0.30 g, 0.42 MPa peak stress and a 44.5 Hz effective point-mass mode. These are stiffness screens, not a claim that a lid-mounted camera is isolated from printer motion. Use thin high-damping pads, the checked height for the required framing, optional suction hold-down and two fixed-object gantry tethers. For critical footage, use a wall/shelf/ceiling or separate desk support that does not touch the printer.

The source traces all four APS-C frame corners. At 20° / 17.25 mm, the nominal view covers 77.1% of the bed and the optical axis lands 58.8 mm toward the front of centre. After widening both vertical field edges by 2°, they cross the clear glass with 23.4 mm front and 15.2 mm rear margins; the limiting AMS ray passes 14.6 mm below its base. The nearest sensor-to-bed distance is 262.4 mm, beyond Sony’s documented 0.25 m wide-end minimum; the moving camera, cage, clamp, cooler, open LCD and saddle retain 4.6 mm nominal solid clearance. Confirm the live view because focus breathing, Active mode and crop settings can alter real framing.

With the AMS removed, the printer sits 155 mm farther rearward beneath the deeper no-AMS footprint. At the 320 mm default, the 0° / 16 mm optical axis is centred on the plate and the nominal frame covers 100.0%, extending at least 11.4 mm beyond every bed edge, with 70.1 / 144.1 mm buffered glass margins and 371.8 mm nearest focus distance. Its conservative free-tip thresholds are 0.379 / 0.698 / 1.118 g (front/rear/side), before suction cups or fixed-object tethers. Test the vent unloaded and monitor the camera: Sony specifies a 40 °C maximum operating temperature.

A modular drawer system with a choice of standard 42 mm Gridfinity receiver field or a plain 3 mm flat floor. Bins locate directly in the receiver version with no separate baseplate; the flat version is unobstructed general-purpose storage. The compact housing width is 96 mm at 2 cells and 42 × width + 15 mm at 3–7 cells; depth is 42 × depth + 12 mm. Sizes at least 3 cells wide retain 4 mm housing and 3 mm drawer walls; 2-wide sizes use localized 3 mm housing / 2.5 mm drawer side walls while retaining the normal front, rear, top and bottom thicknesses.

V1 is a prototype release. Its geometry and exported meshes are validated, but the 3 kg per drawer / four modules high target still needs physical creep and tip testing.

Sizes

Sizes are width × depth. Every combination from 2×2 through 7×7 is included: 36 footprints, each accepting Gridfinity bins up to 6U, 12U, 18U or 24U high.

• 2×2: 96 × 96 mm housing, 89 × 91 mm drawer.
• 5×5: 225 × 222 mm housing, 216 × 217 mm drawer.
• 6×6: 267 × 264 mm housing, 258 × 259 mm drawer.
• 7×7: 309 × 306 mm housing, 300 × 301 mm drawer.
• Sizes through 5×5 have A1 / X1 / P1 and H2-series profiles; any 6- or 7-cell axis is H2-series-only.
• 6U / 12U / 18U / 24U: 66 / 108 / 150 / 192 mm housing heights and 56.5 / 98.5 / 140.5 / 182.5 mm drawer heights.

Every receiver cell centre has a shallow 24 mm tapered top pad and matching bottom recess on the same 42 mm lattice. One smaller housing can locate at any valid cell-aligned position on a larger housing; multiple smaller housings are not an additive tiling system. The interface is locating only: it does not latch, clamp or make an unanchored tall stack safe.

Floor, wall and label options

Each size has 32 variants from four heights and three independent options: integrated Gridfinity or plain 3 mm floor; solid or vented walls; and no label panel or a recessed LetraTag panel. Taller files add _12u, _18u or _24u after the size, followed by _flat_floor, _vented and _labelled as selected. Existing 6U names remain unchanged. The flat floor adds 3.2 mm of clear internal height without changing the outer dimensions.

The vented housing opens only its two side walls. The vented drawer opens its front, rear and both sides in the repo’s pointy-top hex pattern—complete 7 mm holes on 2 mm ribs inside an equal 7 mm outer frame—while keeping the Gridfinity floor solid. The rear receives the uninterrupted full field; only the front reserves the handle and label. Every drawer has a wide, top-open handle with rounded lower corners.

The optional fixed panel is recessed 0.4 mm within the front wall for a cut-to-length strip of standard 12 mm DYMO LetraTag tape, so it cannot rub on the drawer above or droop at the front. It is 51 × 13 mm on 2-wide drawers and 58 × 13 mm on wider drawers. There is no separate printed label tile.

Gridfinity compatibility and checks

The integrated receiver follows the open Gridfinity specification and the reference profile in gridfinity-rebuilt-openscad: 42 mm pitch, 41.5 mm feet and the standard tapered baseplate profile. It sits over a 1.2 mm continuous skin. V1 has no magnet or screw pockets; ordinary bins still seat and locate normally. Flat variants replace the complete receiver with a continuous 3 mm plate and contain no sockets.

Every build checks a full-footprint reference bin at its selected height seated in the receiver or resting on a flat floor, against both drawer and housing; it also checks a drawer fully inserted and halfway removed, two stacked housings, and complete material across every flat floor. A separate exact sweep checks all 3,136 legal smaller-on-larger positions (50,176 combinations across the four-by-four height pairs), including a 0.5 mm minimum gap to every unused pad. All common volumes are zero. All 2,304 STEP downloads are paired with closed, solid preview meshes that agree with their source solids.

Printing

• PLA, 0.4 mm standard-flow nozzle, 0.16 mm layers, textured PEI plate.
• Five walls, 40% gyroid, six top and five bottom layers.
• 5 mm outer brim, no supports.
• Housing rear-down; drawer floor-down. The files are already oriented.
• Footprints through 5×5 have A1 / X1 / P1 and H2-series profiles; any footprint with a 6- or 7-cell axis is H2-series-only.
• Supplied profiles use 60 mm/s outer walls at 1,500 mm/s², 80 mm/s internal solid infill and a 15 mm³/s PLA flow cap. They keep outer-wall speed independent of layer-time cooling and turn the auxiliary fan off to reduce hull-line bands at the floor/rear-to-wall transitions. Keep the fixed 0.16 mm layers unless a manually smoothed local detail band is needed; automatic adaptive layers can create additional speed and flow transitions.

PLA keeps the broad parts flatter and stiffer on an open A1, but it is not for a hot car, direct sun or a hot shed. For sustained temperatures around 40–45 °C or above, use PETG or a more heat-resistant material and calibrate the slide fit for that material before committing to a complete drawer.

Four discreet slip-on feet for the black/brown IKEA ÅLHULT extendable table (306.007.84). Each projects only 2.35 mm beyond the measured leg faces and raises the owner’s table by exactly 10, 15, 20 or 30 mm from its bare wooden legs. This version is for a table assembled without the factory press-in floor glides; the wood leg bears directly on a broad structural land.

• Pocket for a 62.73 mm square leg with R2 corners, with 0.35 mm clearance per side.
• Four shallow guide ribs leave 0.10 mm per side locally, begin above the bearing seat and taper at the rim.
• Two orthogonal concealed 3 × 1.2 mm air grooves cross the complete seat and meet the open side clearance at four points, so removal cannot form a suction cup beneath the flat leg.
• One part alone is screened at a deliberately conservative 5.0 kN load: 1.40 MPa on the bearing land and 1.89 MPa through the 6-wall / 50% gyroid axial section, giving a 5.3 overall factor against the design’s conservative 10 MPa long-term printed-PETG allowance.

Print four in black PETG, broad floor face down, no supports, with a 0.4 mm standard-flow nozzle, 0.20 mm layers, 6 walls, 50% gyroid, 8 top and 6 bottom layers. Print one first to verify the measured fit, then make three more. Fit every extender with the table unloaded, verify that each leg is fully seated, and do not drag the raised table sideways. To remove one, lift that table corner and pull straight down with a small rocking motion; no prying is needed.

Do not add the factory glides without revising the seat geometry. This independent accessory is not made, approved or endorsed by IKEA.

Empty Gridfinity bins for dividing the modular drawers into whatever combination of footprints a job needs. Every width × depth combination from 1×1 through 7×7 is available at 6U, 12U, 18U and 24U. They lock directly into the drawers’ integrated 42 mm receiver floors and also work with ordinary compatible baseplates.

Each bin has the standard foot and stacking geometry, four glue-fit magnet pockets per cell, and an internal ledge ready for the optional removable lid. The ledge’s 45° underside prints without starting a shelf over air. There are no fixed dividers inside.

Sizes and options

The complete catalog has 1,568 variants: 49 footprints × four heights × solid/vented × plain/labelled × open/lidded.

• Footprints follow 42 × cells − 0.5 mm: 1×1 is 41.5 × 41.5 mm, 5×5 is 209.5 × 209.5 mm, 6×6 is 251.5 × 251.5 mm, and 7×7 is 293.5 × 293.5 mm.
• 6U / 12U / 18U / 24U nominal rims are 42 / 84 / 126 / 168 mm. The printable stacking crown adds 3.8 mm.
• Solid variants have continuous sides. Vented variants open all four side walls in the pointy-top hex pattern while keeping the floor solid; a supplied lid is vented too.
• Labelled open bins have a small front-left adhesive-label platform visible from above. Labelled lidded bins put the 22 × 9 mm label recess on the lid.
• Lidded variants add a separate gravity-fit lid with a finger notch. It sits below the rim, so the bin remains stackable and does not become taller.

Sizes through 5×5 have A1 / X1 / P1 and H2-series profiles. Any footprint with a 6- or 7-cell axis is H2-series-only: the 251.5 mm six-cell part leaves too little real margin for the required brim on a 256 mm bed, and seven cells exceed it.

Compatibility and checks

The interface follows the open Gridfinity specification and the documented Gridfinity Builder geometry: 42 mm pitch, 0.25 mm outer-side clearance, 4.75 mm feet, 7 mm height units and the trimmed 3.8 mm stacking crown. Each cell has four ⌀6.5 × 2.4 mm pockets on 26 mm centres for nominal 6 × 2 mm magnets. Use adhesive; fit varies by printer.

Every build checks receiver insertion, upper-bin insertion and settled stack positions, lid contact and upper-foot clearance, exact outside dimensions, all magnet pockets, and the matching compact drawer envelope. The drawer gives a full-footprint bin 0.25 mm at each side and 0.75 mm at the front and rear.

Printing

• PLA, 0.4 mm standard-flow nozzle, 0.16 mm layers, textured PEI plate.
• Five walls, 40% gyroid, six top and five bottom layers.
• 5 mm outer brim, no supports.
• Bin floor-down; lid flat. The files and profiles are already oriented.
• Vented profiles cap the part and auxiliary fans at 50% to reduce uneven cooling across broad floors.

Print the separate fit coupon before a large run. It contains a receiver, low 1×1 bin and real lid, but is deliberately not part of this listing. PLA is not appropriate for a hot car, direct sun or a hot shed; repeat the fit test if changing material.

Gridfinity bins that hold one camera lens each, for the modular Gridfinity drawers or any standard 42 mm baseplate. Each bin is a solid block with the lens’s outline cut out of it, so the lens sits in a cradle instead of rolling around an empty bin, on the same feet and four magnet pockets per cell as the empty bins.

Lenses

Lens	Sits	Bin	Lens above the rim	Drawer
Sony SELP16502 · E PZ 16-50mm F3.5-5.6 OSS II	standing, on its rear cap	2×2, 6U	9.9 mm, with finger reliefs	6U
Sony SEL90M28G · FE 90mm F2.8 Macro G OSS	lying along the bin	4×3, 6U	42.6 mm	12U
Sigma 4214965 · 17-40mm F1.8 DC | Art, Sony E	lying along the bin	4×3, 6U	36.5 mm	12U

The bins are sized from the makers’ published envelopes with both caps on (10 mm allowed behind the flange for the rear cap, 5 mm in front of the filter ring for a pinch cap). Hoods are not allowed for: store them off the lens. The lens stands above the rim by design, so check the drawer column: a 6U lens bin can need a 12U drawer.

How a bin is derived

• A lens longer than it is wide, caps on, lies on its side along the bin in a trough; a shorter, wider one stands on its rear cap in a round pocket. 1 mm of clearance around the barrel, 1.5 mm past each end of a lying lens.
• The footprint is the fewest cells that keep 2.5 mm of material around the cavity and a 9.5 mm label band along the front edge.
• The height is the tallest standard height that leaves 20 mm of the lens above the rim to lift it out; a lens that cannot leave that much even at 6U gets finger reliefs at both ends of its cavity. There is no stacking lip: the lens always stands proud.
• Every bin carries the same label in the same place: the maker and model code in 5.5 mm capitals, engraved 0.6 mm into the top face along the front edge and filled by a separate inlay for a second colour.

Compatibility and checks

The Gridfinity interface is the empty bins’, imported rather than copied: 42 mm pitch, 0.25 mm outer-side clearance, 4.75 mm feet, and four ⌀6.5 × 2.4 mm pockets per cell on 26 mm centres for nominal 6 × 2 mm magnets, glued. Every build checks the feet in a receiver field, every magnet pocket, the exact footprint and rim, the capped lens resting in its cavity and grown to just under the clearance, the label’s fit and stroke width, and the drawer the lens fits under.

Printing

• PLA, 0.4 mm standard-flow nozzle, 0.16 mm layers, textured PEI plate; black for the bin, white for the label.
• Five walls, 15% gyroid inside the block, six top and five bottom layers.
• 5 mm outer brim, no supports, floor down. The files and profiles are already oriented.
• One project per printer family with every lens on its own plate.

PLA is not appropriate for a hot car, direct sun or a hot shed.

Keep USB-A, USB-C, HDMI, Ethernet, C13 power leads and other cables in separate compartments. Each bin has two or three compartments separated by fixed partitions, a shared removable lid, and standard Gridfinity feet and a stacking rim. The lid sits below the rim, so closed bins of the same footprint still stack.

Choose a size

Measure a loosely coiled cable including both plugs and any tie. Choose by those dimensions, rather than the connector type or cable length: a thick HDMI lead and a thin USB lead of the same length take different space. Keep a relaxed bend; a cable that exceeds the largest envelope needs a larger bin.

Footprint	Compartments	Usable width × length per cable
2×3	2	34 × 116.5 mm
3×4	2	55 × 158.5 mm
3×4	3	34.5 × 158.5 mm
4×5	2	76 × 200.5 mm
4×5	3	48.5 × 200.5 mm

Every layout comes in 6U with 33 mm usable bundle height, or 12U with 75 mm. The measurements include clearance to lift the whole cable straight out past the lid ledge. Printed external heights are 45.8 and 87.8 mm. External footprints are 83.5×125.5, 125.5×167.5 and 167.5×209.5 mm respectively.

Lids and stacking

The 2.5 mm dividers run from the floor to 0.3 mm below the shared 1.6 mm lid. A lift notch over the first compartment stays clear of the divider. Keep coils below the divider tops. The lid rests in place by gravity; it has no latch and is intended for upright storage, not transport or a dust-tight seal.

Stack matching footprints so the upper bin rests on the perimeter rim. Its feet clear the lower lid by 0.20 mm. Do not use the thin lid as a shelf for smaller bins whose feet miss that rim. In a receiver drawer, 6U bins stack one/two/three/four high in 6U/12U/18U/24U drawers; 12U bins fit one high in 12U or 18U drawers and two high in a 24U drawer. Each count leaves at least 3 mm headroom. Remove upper bins to reach lower ones.

The standard 42 mm Gridfinity feet fit the modular drawers’ receiver floors. Plain-floor drawers also have clearance but do not positively locate the bins. Four optional Ø6.5×2.4 mm glue-fit pockets per cell take nominal 6×2 mm magnets. Magnets are not needed for ordinary drawer use.

Printing

PLA, 0.4 mm standard-flow nozzle, 0.16 mm layers, five walls, 40% gyroid, six top and five bottom layers, 5 mm outer brim, textured PEI plate, no supports. Print the bin floor-down and the lid flat. The single-filament profiles are grouped by footprint and height for the X1/P1/A1 family and H2 series, with a separate named lid plate where needed.

Geometry and exported meshes are numerically checked, including actual drawer fit, stack seating, lid clearance and continuous partitions. Physical print and real-cable fit testing remain to be done. Start with a small bin and lid before printing a set. The translucent coils in the images are illustrative, not a particular cable specification.
