Bandsaw Miter Gage

This is a printed miter gage for a bandsaw. It is designed to fit a 20mm channel. It has a slot for adjustment between -45° and +45° and there are discrete settings for +/-60°, +/-30°, +/-22.5°, and 0°. I am using Slic3r to generate G-code. SketchUp files are included. 2016-01-24 Update: Cleaned up Sketchup file.
