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.
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.
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 4 And Pi Zero Standoff Drilling Template
A drill-guide template for project boxes. It matches the 85 x 56 mm Raspberry Pi 4 board outline and has 8 mm-tall guide bushings on both the Pi 4 58 x 49 mm pattern and the Pi Zero 58 x 23 mm pattern, so standoff holes in a stock box without bosses line up the first time. The 2.9 mm bores take a 2.5–2.8 mm bit or a scribe. Open windows show the box floor underneath, and V-notches at the pattern centre let you line it up with marked centre lines.
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.
