A simple angle jig for 15, 22.5, 30, 36, 45, 54 and 67.5 degree angles. I use them to make inserts into 60 and 108 degree corners for my icosaeder and dodecaeder lamps. The other angles are used in Asanoha Kumiko. I printed it with 15% Infill, gyroid infill pattern and with a modifier at the stop block with 35% infill and 6 wall loops.
