- 3D Print Files (STL, G-code, etc.)
I was tired of searching for throw gauges or printing new ones. This protractor is 2 1/2" per side so it's small enough to measure control surfaces and can go positive or negative. It has major divisions at 10° and minor at 2°. I made the outside so that it easily pinches against the inside to hold your angle. The one in the picture is printed in two filament colors using Prusa Slicer.
Printed in PETG with 25% triangular infill - though I don't think it really matters. The pivot is an M2x12 screw & nut. The inside piece prints flat, the outside piece prints vertically with supports (organic if you're using Prusa).
