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.
