I used 0.10mm detail for the shaft and c-clips, but 0.20mm detail for the protractor and arm. It seemed to work fine.
15% infill
The tolerences are a bit tight, so you may have to adjust.
The part of the shaft for the c-clips is 4.5mm in diameter and 2mm tall.
You just need one of everything exept for the c-clip. You need two c-clips.
All you have to do is align the arm with one angle, and the protractor with another angle. the slots in the arm let you see the angle of the protractor.
