A standoff bridge that suspends a 40 mm fan directly over a Raspberry Pi 4B / 3B+, with a 32 mm shrouded duct collar aiming the air at the SoC instead of letting it spill sideways. 74 x 64 mm plate on four 18 mm legs that clear the USB/Ethernet stack, 58 x 49 mm M2.5 board pattern with captured nuts at the board end, 32 mm square M3 fan pattern, plus side exhaust vents and a 26 x 4.5 mm slot for GPIO ribbon or camera flex.
A stackable 96 x 84 x 28 mm deck for Raspberry Pi 4B / 3B+ cluster builds: each board bolts to four 6 mm standoffs on the verified 58 x 49 mm pattern with 2.9 mm holes for M2.5 screws, and the 14 mm corner posts peg into the socket of the deck above for a 28 mm stack pitch (16 mm of free air over each board for a HAT or fan). Three large windows give vertical airflow, plus two 4 mm cable-tie slots and two M3 clearance holes so the bottom deck can be screwed to a wall or panel.
A split-clamp pillow block that carries two LM8UU linear bearings (15 mm OD x 24 mm) in line on an 8 mm smooth rod, with a centre rib that stops the bearings against each other and two M3 clamp screws that pinch the flanks so nothing walks out. The 60 x 44 x 35 mm body bolts down through four M4 clearance holes on a 40 x 34 mm rectangle, putting the rod axis 21 mm above the mounting surface.
A 110 x 62 mm vented backplate for a Raspberry Pi 4B / 3B+ with four 5 mm standoffs on the 58 x 49 mm bolt pattern (2.9 mm bores for M2.5 screws), edge stiffening ribs, two keyhole slots that drop over #8 wall screws, an M4 lock hole at the bottom, and a zip-tie bridge for power-cable strain relief. Five long vent slots keep air moving under the board and cut print time.
A 96 mm wide funnel whose 45° cone seat drops into and self-centers on any jar mouth from 46 to 84 mm, so one funnel covers both regular and wide-mouth mason jars. Two side fins give a no-slip grip while you pour rice, beans, or jam; 48 mm tall with 2.2 mm walls.
