Printable Protractor

I have a new project I'm working on, but I needed to have an idea of the angles involved. I couldn't find a protractor, so I made one. :)

The protractor has two sets of angle-finders, an inner and an outer ring. The marks on each ring are 10 degrees apart. The two rings are set 5 degrees from one another.

If you require a greater degree of measurement, you could always edit the OpenSCAD file to include finer gradations. For my purposes, this worked really well.
