Protractor / Goniometer raised numbers, fully printed, no supports

Protractor made with all printed parts, no supports. The numbers and graduations are raised, ideal for 2 colour prints. I did mine by performing a colour change for the last two layers.
I found similar models both here and on Thingiverse, none quite matched what I wanted for myself, and the closest ones didn't have a license that allowed remixes. I figured that it'd be best to design one from scratch that suits me.

The bolt fits into the body with a tapered hex, so tolerance there should be forgiving. The printed nut and bolt were made to be decently loose tolerance, but if they're too tight a fit on your print just scale the nut up ~2% in x and y only not z.

.STEP file is included to allow for easier remixing/customizing.
