TO-220/TO-247 Jack-Screw Heatsink Clamp Bridge
A 62 x 23 x 12 mm U-shaped bridge that clamps a TO-220 or TO-247 transistor or regulator flat against a heatsink. Two M3 screws (3.4 mm clearance holes, 46 mm apart) go through the feet into the heatsink. An M3 jack screw in a 4.0 mm heat-set insert at the top of the bridge presses down on the package, so you don't have to drill and tap through the tab or use an insulating bushing. The opening under the bridge is 18 mm wide x 12 mm high.
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.
Sink Pop-Up Drain Clevis Strap
Replacement clevis strap for a bathroom sink pop-up drain — the flat perforated strap that links the faucet lift rod to the horizontal pivot rod and is the piece that snaps or goes missing when the stopper sticks open. The 88 x 14 x 20 mm part clamps lift rods up to 1/4 in (6.8 mm bore) with an M3 heat-set insert and set screw, and gives five 6.8 mm pivot-rod holes on a 10 mm pitch for 40 mm of stopper-travel adjustment.
Print-In-Place Oldham Shaft Coupler
A three-piece print-in-place Oldham coupling that joins a 5 mm stepper/gearmotor shaft (5.3 mm bore) to an 8 mm smooth rod or shaft (8.3 mm bore) while absorbing parallel misalignment instead of side-loading the bearings. Ø28 mm hubs, 34 mm tall overall; dovetailed sliding tongues keep the stack captive, and each hub has a flat boss bored 4.0 mm for an M3 heat-set insert and grub screw.
Rack And Pinion Linear Drive Block
A print-in-place module-2 rack and pinion linear drive: a 150 mm toothed rack slides through a 60 x 54 mm housing while a 16-tooth pinion (32 mm pitch dia, 100 mm of travel per turn) turns on a 5.3 mm bore for any 5 mm motor or gearmotor shaft, locked with an M3 screw into a captured M3 nut in the top collar. The housing bolts down through four M4 clearance holes and the rack carries two pairs of M3 heat-set bores on top for your carriage — a cheap linear actuator for gate, hoist, feeder and camera-slider builds where a leadscrew is too slow.
Seatstay Clamp Wheel Truing Gauge
A truing gauge that zip-ties to a seatstay or fork blade (12–28 mm round tube sits in the 90° V-cradle) so any bike becomes a truing stand — the 34 mm yoke gap straddles rims up to ~30 mm wide and five M3 screws running in 4.0 mm heat-set inserts act as adjustable feelers: four lateral (two per prong, 20 mm apart radially, so you can land one on the rim sidewall wherever you clamp) and one facing radially outward for hop. 104 x 52 x 12 mm, prints flat with no supports.
