A bench-top fume extractor housing for any 40 x 40 x 10 mm fan — the fan bolts to the 60°-tilted face on its standard 32 mm M3 pattern (3.4 mm clearance holes with counterbores so the heads sit flush), and a 42 mm square of activated-carbon filter sheet press-fits into the 41.5 x 41.5 x 4 mm pocket in front of a ribbed finger-guard throat. Footprint 52 x 64 mm, 50 mm tall, with two M4 holes in the weighted base for bolting it to the bench and an open rear duct so exhaust clears the work.
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 104 x 46 x 16 mm bench dock that stands up 6 microSD cards (11 x 15 x 1 mm), 3 full-size SD cards (24 x 32 x 2.1 mm) and 4 USB-A flash drives parked plug-down in 12.8 x 5.4 mm bays, so the loose media around a Pi/camera bench stops disappearing into the parts bin. Cards protrude 7–20 mm for a one-finger pinch, a scalloped thumb groove backs the microSD row, and two M3 clearance holes on a 96 mm centre let you screw it into a drawer bottom or shelf; underside relief pockets keep it to roughly 57 cm³.
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 six-lane stadium-step rack that sorts cut heat-shrink tubing by diameter — troughs 8/10/12/14/17/20 mm wide take the common 3:1 sizes from 2.4 mm up to 12.7 mm, each 74 mm long with a finger scallop so you can pinch a piece out without emptying the lane. 116 x 99 x 39 mm overall, open underneath to stay light, with two M4 clearance ears (4.5 mm) to screw it to a shelf or bench back.
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 soil spike that turns an empty soda bottle into a slow-drip plant waterer — press the inverted bottle neck into the ribbed socket and push the 140 mm spike into the pot. Three staggered drip ports feed water down at the root zone while the 44 mm flange keeps it from sinking.
A 147 mm staircase block that stands a 13-piece metric drill index upright, with bores from 1.5 mm to 7.5 mm rising left to right so the size order is obvious at a glance. Each step is taller than the last, so bit tips sit deep and shanks stay easy to grab.
