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.
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.
PC Chassis Edge Snap Cable Dress Clip
A screwless cable clip that pushes onto any 0.8–2.0 mm sheet-metal edge, like a PC case rail, a server chassis lip or an enclosure cutout. Its tapered wedge slot narrows from 2.2 mm to 0.6 mm and pinches the panel. On top it has three snap-in C-channels with 7.3, 5.3 and 4.3 mm bores, for coax up to about 7 mm, USB/SATA round leads and fan wires. The clip is 42 x 26 x 15 mm and prints flat, so the snap rings and prongs flex in the strong XY plane.
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.
Flagged: mains electrical wiring. Not for safety-critical use without independent engineering review.
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.
