Stepper driver trimpot aligner / screwdriver tool
If you want to align / set your stepper motor drivers, you need a non-conductive (plastic or ceramic) tool which is cheap but difficult to find. Fear not, because this is a working substitute made with PLA, with phillips and slotted version and screwdriver adapter.Maker/DIY

Notes on HOW TO PRINT IT:
To start, this is a very difficult print. It might not work well in every printer.
Please try to print the shapes exactly as they are given, otherwise it will not work. No support. You can use brim, it worked for me, but you can also print without it. You HAVE to use PLA or another rigid material, because ABS is too flexible for this. I have tested the shapes in many positions and configurations, and these are the only ones which work. In fact, you need a very well calibrated 3D printer to get them right, specially the phillips and slotted tips, because they are quite thin.
The layer height also have to be at most 0.10mm; higher values won't work.
Please CHECK the gcode path before attempting to print! Wrong settings will spoil the print - again, this is a very difficult print. You might want to set XY compensation / horizontal size compensation to a value higher than zero (I have used 0.10mm) if the tip ends do not appear.
Materials and methods
No extra materials are needed, but you can use the hexagon handle to fit in a common screwdriver handle.
