A four-link cable drag chain with an integrated M3 mounting foot, printed fully assembled — no pins, no clips, no post-assembly. Each 32 mm link carries an 11 mm wide x 13 mm tall cable channel and an arc-slot bend limiter that stops the chain dead straight and allows 35 deg of bend, so the top run won't sag. Overall 170 x 29 x 16 mm; the foot takes two M3 screws on a 19 mm spacing.
A 62 mm square, 19 mm tall adapter that lets a NEMA 17 stepper bolt into a machine face drilled for NEMA 23 — the base carries the 47.14 mm M5 pattern, the raised Ø52 tower carries the 31 mm M3 pattern with a 22.4 mm pilot register for the motor's centring boss. The hollow Ø30 core clears a shaft coupler, a 14 mm side window gives Allen-key access to the coupler set screw, and counterbores in the base bottom fully recess the four M3x20 motor screws so the adapter still seats flat.
A 60 mm OD × 18 mm wide spoked drive wheel that slips onto any 5 mm motor shaft (NEMA 17, 37 mm gearmotor) and locks with an M3 set screw threaded into the 6.3 mm hub wall. The 8 mm × 2.5 mm rim groove seats a #64 rubber band as a tire, and 24 scallops in the flanges give traction if you run it bare — replaces the hub-and-tire set nobody stocks for one-off robot builds.
A countertop vanity dispenser: a 61 mm tube that stacks standard cotton rounds with a full-height front slot so you can see the level and pull one out with a thumb, plus an attached 28 mm cup for cotton swabs. Footprint 98 x 66 mm, 82 mm tall.
An open-top can that swallows a ball of jute or sisal twine (80 mm inner diameter, 80 mm deep) and feeds it out through a guide eyelet, with a pinch slot on the lip that grips the loose end so it never falls back inside. A keyhole on the flat back hangs it on a single screw in the shed or potting bench, or it just sits upright on the bench.
A gravity-fed dual-channel dispenser that stacks 6 AA and 8 AAA cells and drops the next one into a front grab window with a retaining lip. Stands 92 mm tall on a shelf or screws to a wall through the two rear ears.
