Personal CAD models for 3D printing, written as Python code. Every part here is built from its source on each change, with a 3MF to print and a STEP to measure or modify.
Replacement for the Canyon EP403-16 "Leitungsführung" (part E403-16), the small plate under the bottom bracket that covers the frame's cable port. A slit with a keyhole at its end lets it slide over a hose that is already in place; two small screws hold it. Canyon lists it as sold out, without dimensions or a list of frames (product page; it is also part of the GP7067-01 cable routing kit, "for all Canyon AL frames with special designed clip loops").
Stopper for a curtain rail (Gardinia profile 4460). It sits entirely inside the lower (glider) channel and is clamped anywhere along the rail with a set screw.
Drill template for mounting handles on doors.
Sliding coupling for a built-in fridge ("Einbaukühlschrank Gleitschiene", drag-door / Schlepptür fitting): the kitchen's furniture front hangs on its own hinges, and the fridge door follows it through a slider running in a rail. The doors pivot about different axes, so the slider runs along the rail as they open. Idea from printables 587358, redesigned:
