A four-step sacrificial bleed block / pad spacer for hydraulic disc brakes: slide it into the empty caliper and stop at the thickest step that fits (9, 11, 13 or 15 mm) to hold the pistons fully retracted while you bleed or swap pads. 99 x 26 x 15 mm with 45-degree lead-in ramps on the nose and every riser, 1-4 dimples marking each step's thickness, and two 5.5 mm M5 holes on 10 mm centres in the handle so it hangs on a hook or screws to the toolbox lid.
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 cable-tie-on bottle cage mount for bikes with no braze-on bosses: a 26 x 26 x 90 mm block with a 90-degree V groove that self-centres on round tubes from about 22 to 32 mm, and two M5 cage bolt bores on the standard 64 mm boss spacing with captured 8 mm hex nuts loaded from the side. Two 8 x 2.8 mm tunnels take 4.8 mm standard or 7.6 mm heavy-duty zip ties that wrap the tube and pull the groove down onto it.
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 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 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.
A 60 mm one-piece carabiner whose gate is a built-in flexing spring arm — press it inward to hook on, and a capture nose stops it opening under load. Prints flat with no supports, no assembly, and no metal spring; sized for keys, water bottles, and bag straps.
