80 mm Fan Snap-On Fabric Filter Cap
This cap fits over a standard 80 x 80 mm fan frame without screws and holds a square of washable filter fabric (nylon mesh or stocking) against the fan face. Four flexible side tabs with 45° detent ridges catch behind face flanges up to about 4.5 mm thick. The pocket is 80.6 mm square inside and 84.6 mm square outside, and the grid has a 6 mm pitch. It keeps dust out of project boxes and open PC builds, and it lifts off for cleaning.
Serpentine Fin Cable Strain Relief Block
A strain relief that screws inside a project box at the point where the cable exits through the wall. You press a 3–5 mm DC barrel, JST or 2-core lead into a channel with three alternating fins. The fins force it into an S-bend, so a pull on the cable outside doesn't reach your solder joints. It's 60 x 22 x 14 mm, mounts with two M3 screws (3.4 mm holes on 50 mm centres) and has a zip-tie slot that runs under the floor if you want extra grip.
1590B-Size Printed Stomp Box Enclosure
A guitar pedal enclosure with the same 112 x 60 x 31 mm outside size as a Hammond 1590B. The walls are 2.5 mm thick and the top is 3 mm. Each corner has a boss with a 4.0 mm bore for an M3 brass heat-set insert, so you can screw on a flat aluminium or printed base plate. The 3 mm pilot holes mark a footswitch, three pots, an LED, in/out jacks and a DC jack. Step-drill each one to fit your parts, so you don't pay for an $8–15 metal box just to hold a perfboard build.
120 mm Fan Standoff Finger Guard
A finger and wire guard for a bare 120 mm axial fan. It bolts on through the standard 105 mm square hole pattern with 4.5 mm holes that take fan screws or M4 bolts, and a 3 mm built-in standoff ring holds the concentric grille clear of the blades. The guard is 120 x 120 x 5 mm. The ring gaps are about 7.5 mm, small enough to keep fingers and loose leads out of a fan you've pulled for a DIY amp, PSU or rack build.
Flexure Snap Latch For Project Box Lids
A screw-on flexure latch for DIY project boxes. A 34 x 24 x 5 mm pad bolts to the box wall with two M3 screws (3.4 mm clearance holes, 20 mm apart). A 2 mm thick, 16 mm wide spring arm ends in a hook with a 3.5 mm catch and a ribbed thumb tab, so the lid snaps shut and lifts off without tools.
Pi 4 Edge-On DIN Rail Snap Mount
This mount holds a Raspberry Pi 4B or 3B+ edge-on to a standard 35 mm TH35-7.5 DIN rail (1 mm flanges). The board sits on four M2.5 standoffs on the 58 x 49 mm hole pattern and stands at right angles to the rail, so it takes up roughly 25 mm of rail instead of 85 mm. On the 92 x 87 mm plate, a fixed hook grips one rail flange, a flexure latch snaps over the other, and you release it by twisting a flat screwdriver in the slot.

Pi Zero Outdoor Sensor Node Gland Box
A wall-mount base tub for outdoor Home Assistant and garden sensor nodes. It measures 90 x 60 x 36 mm and has a 3 mm wall. Inside are Pi Zero standoffs on the 58 x 23 mm pattern with 2.9 mm M2.5 holes, counterbored from the back. Two 12.6 mm holes in the bottom wall take M12 or PG7 cable glands, so sensor leads come in from below and water runs away from them. There are four M3 heat-set insert bosses with 4.0 mm bores for the lid, a 3 mm flat rim for foam gasket tape, and slotted wall ears for #8 screws.

50 mm Flared Bass Reflex Port Tube
Screw-in bass-reflex port for car-audio and home speaker boxes: 50 mm bore, 100 mm long, 45° flares at both ends, on a 96 mm flange. Drill a 73 mm (2-7/8 in) hole-saw hole in the baffle, then fix the port with four #8 wood screws through 4.8 mm clearance holes on an 84 mm circle. No more routing MDF ports, and it prints upright with no supports.
Five-Slot Vertical PCB Card Guide Rail
A 130 mm floor rail with five 2.0 mm slots on a 20 mm pitch. Two rails screwed to an enclosure floor hold 1.0–1.6 mm perfboards or PCBs upright, so you don't need standoffs. Each slot is 7 mm deep with a V lead-in so boards drop in easily. The rail mounts with two M3 screws (3.4 mm holes on 120 mm centres).
Six-Post Bench PSU Terminal Pod
A 110 x 45 x 40 mm sloped desk pod for three pairs of binding posts on standard 19.05 mm (0.75 in) dual-banana spacing, with the pairs 35 mm apart. It moves the outputs of an ATX or bench power supply to the front of the bench. It has a 10 mm rear cable entry and four M3 self-tap bosses for a flat bottom plate.
22 mm Snap-In Step-Down Cable Grommet
A snap-in grommet for a 22 mm hole (the common step-drill size) in a project box, dash or panel wall up to 3 mm thick. It has a 36 mm flange, four barbed spring fingers and a knock-out membrane with score rings at 4, 7, 10 and 13 mm. Trim to the ring that matches your cable and you get a snug pass-through, not a loose hole.
DE-9 CAN Bus Bench Breakout Box
An 80 x 60 x 35 mm bench breakout box for CAN bus work. A panel-mount DE-9 connector goes in the front: 20 x 11.5 mm window and 3.4 mm screw holes 25 mm apart. The back has four M4 terminal-stud holes (4.5 mm) so you can clip probes onto CAN-H, CAN-L, GND and power. The lid screws into four M3 heat-set insert bosses at the corners.
HDMI And USB-C Plug-Through Cable Bulkhead
This screw-on bulkhead plate lets an HDMI or USB-C cable with the plug already fitted pass through a project-box wall. Cut a 30 x 16 mm window in the enclosure and push the plug through. Slide the cable sideways into the 8 mm slot (cables up to about 7.5 mm OD), then fix the 64 x 44 x 3 mm plate over the window with four M3 screws on a 52 x 32 mm pattern. The half-pipe saddle on the plate is 23 mm tall and has two 4 mm zip-tie grooves that hold the cable, so a tug on the cable doesn't pull on the port inside.
Pi 4 And Pi Zero Nut-Track Project Box
A 120 x 80 x 32 mm project box. Its 4.2 mm floor has four captured M3 nut tracks spaced for both the Raspberry Pi 4 (58 x 49 mm hole pattern) and the Pi Zero (58 x 23 mm), so you can bolt a board anywhere along the tracks. It has cable notches in both ends, vent slots in the side walls and four M3 heat-set insert bosses (4.0 mm bore, 8 mm deep) for screwing on a flat lid.
Pi Zero Vented Wall Tray
This open-front wall tray holds a Raspberry Pi Zero, Zero W or Zero 2 W on its 58 x 23 mm hole pattern. The four 6 mm standoffs have M2.5 clearance holes and head recesses underneath, so the screws sit flush against the wall. The 71 x 36 mm tub has a lowered wall along the port side and notches at both ends so the SD card and camera ribbon stay reachable, a slotted floor for airflow, and two ears with slots for #8 (4.2 mm) wood screws so you can mount the Pi flat to a wall, shelf or cabinet side.
Pi Zero Snake Head
The open-top head from the 'SG90 Wheeled Serpentine Snake Robot' kit. It measures 90 x 36 x 33 mm and holds a Raspberry Pi Zero or Zero 2 W on four 6 mm standoffs spaced 58 x 23 mm, fastened with M2.5x12 screws and nuts. The 4 mm rear wall has four 3.4 mm holes and bolts to the first segment housing with M3x12 SHCS. The front face has four M3 heat-set bores (4.0 x 8 mm) on the same 16 x 20 mm pattern for sensor plates. A split port window in the left wall gives access to the Pi's USB and mini-HDMI connectors.
Acrylic Panel Enclosure Corner Post
A corner post for building custom project boxes out of 3 mm acrylic, plywood or scrap FR4: the side panels slide into two 3.3 mm grooves (3 mm stock + 0.3 mm clearance, 19 mm engagement) and the base and lid screw into M3 brass heat-set inserts at each end (4.0 mm bore, 6 mm deep). Post is 50 mm tall with 30 mm legs, 9 mm thick; print four and cut panels to whatever size your PSU, amp or controller board needs.
Dual Keystone Surface Mount Box
A printed surface-mount "biscuit" box that holds two standard keystone modules (RJ45, USB, HDMI, F-type) in 14.8 x 16.3 mm snap openings through a 2.0 mm front panel — the 14.5 x 16.0 mm cutout and panel thickness keystone latches are built for. Outer size 72 x 40 x 34 mm, 22 mm port pitch, two 4.5 mm wall-screw bores (M4 or #8 wood screw, 4.2 mm shank) sunk at the back plate behind a 9 mm screwdriver channel, plus 12 x 12 mm cable notches on both long walls and a zip-tie strain-relief slot pair.
Print-In-Place Quarter-Turn Cam Latch
A quarter-turn cam latch that prints as one piece with a captive rotor — no pin, screw or spring to add. The 56 x 40 x 4 mm plate screws to a door or access panel with two countersunk #8 (4.2 mm) or M4 screws 22 mm apart, and the thumb knob turns a cam reaching 32.5 mm from the spindle axis, 10.5 mm past the plate edge, to hook behind a frame lip up to 9 mm proud of the mounting face. Moulded posts hard-stop the sweep at 90° and a detent bump snaps the cam into the open position so it stays clear; overall height 19 mm.
Mast Pipe Enclosure Saddle Clamp
A 72 x 80 mm mounting plate with two 90-degree V-jaw ribs spaced 50 mm apart that cradle a 20–48 mm OD mast pipe (3/4 in to 1-1/2 in conduit or fence rail) and pull it in with two standard 12.7 mm stainless worm-drive hose clamps threaded through the moulded band tunnels. The V-groove plus the 50 mm rib spacing stops the wind-twist you get from U-bolts alone; the plate carries four M4 clearance holes on a 56 x 40 mm pattern for a junction box or printed LoRa/solar node enclosure and an 18 mm centre pass-through for a cable gland or drainage.
Hole-Free PCB Edge Clamp Carrier
A 92 x 54 mm carrier plate that mounts bare PCBs with no mounting holes — the fixed rail and a print-in-place dovetail jaw grip the board edges with 1.2 mm retaining lips, covering board widths from 11 to 65 mm of standard 1.6 mm FR4. The jaw locks with an M3 screw into a heat-set insert (4.0 mm bore) that jacks the dovetail tight, and the plate has four M3 clearance holes plus two zip-tie slots for cable strain relief.
GX12 Panel Flange With Strain Relief
A 52 x 36 x 4 mm bolt-on flange that gives a GX12 aviation connector a proper 12.4 mm mounting bore with an 18 mm nut counterbore, so you can add a connector to a project box — or cover a ragged, oversized 15–24 mm hole — instead of epoxying the connector in. Four M3 clearance holes on a 42 x 26 mm pattern hold it to the panel, and the 16 mm gusseted post behind it has a zip-tie slot and a 8 mm cable saddle so a yank on the loom loads the plastic, not your solder joints.
Bulkhead Cable Gland Clamp
A screw-tightened cord grip that bolts inside a project box and clamps a 4.5–7 mm round cable so pulls on the lead never reach the solder joints. The 7 mm bore has three grip ribs and a split jaw closed by one M3 x 25 screw with a captured M3 nut; the rear flange bolts down with two M3 screws on 26 mm centres. Overall 40 x 34 x 20 mm, prints flat with no supports.
Flagged: mains electrical wiring. Not for safety-critical use without independent engineering review.
DIN Rail Pi Zero Snap Mount
A 66 x 44 mm adapter plate that snaps onto standard 35 mm top-hat DIN rail (TS35) and carries a Raspberry Pi Zero / Zero 2 W on its front face via the 58 x 23 mm hole pattern, plus two spare M3 holes for any other small module. One rigid hook grabs the first rail flange; a 30 mm sprung tongue with a pull tab grabs the second, so boards clip on and off the rail in a second without unscrewing anything — ideal for putting hobby sensors and controllers into a real home-automation or garage panel.
