etc: simple button/coin cell battery holder Needed a holder for leds inside of my acorns, super simple holder with room for an led at the top and a wire hole on the side. Intended to be printed from flexible material (TPE or TPU) for a snug fit. Might work in rigid filament if slot_undersize is reduced, but no guarantees.
simple foot for cheap storage rack I got a cheap "muscle rack" and the metal posts themselves are the feet. Not a great combo with laminate wood flooring... Just a quick openscad hack to generate anti-scratching feet for the racks. Reasonably customizable. Released public domain/CC0.
power supply: loosen power socket mount Tolerance was too close and edges had to be filed down. Socket can be a bit loose since it has both a snap in connector and mounting bolts. One defect: it's pretty impossible to use the bolt hole nearest the faceplate. Haven't had issues just using one.
