Stepper driver trimpot aligner / screwdriver tool

thingiverse

If you want to align or set your stepper motor drivers, you'll need a cheap but hard-to-find non-conductive tool made from plastic or ceramic. Fear not - this works as a substitute: I designed and printed one using PLA. The design includes Phillips, slotted versions and screwdriver adapters. Print Settings: Rafts: No Supports: No Resolution: 0.1 Infill: 15% Notes: * First off, this print is super challenging and might not work with every printer. Try to print the shapes exactly as drawn or it won't function correctly. No supports are needed, but you can use a brim if that works for you. I've tested these designs in many different positions and configurations and these are the only ones that succeed. You need an incredibly well-calibrated 3D printer, especially to get the thin Phillips and slotted tips right. The layer height needs to be no more than 0.10mm or it won't work - higher values will mess it up. Always verify the G-code path before attempting a print! Incorrect settings will ruin the print; this one's tough enough without making errors. If you need a hexagon handle for screwdrivers, feel free to use it - it's common and easy to fit into standard handles.
