Router Table Mitre Gauge

Mitre Gauge for a router tableI used a cheap protractor glued in to the centre, use what you feel best suits or just use the outer marks.I have put larger marks at 90, 45, 30, 22.5It seems very accurate to me, I have used it a fair bit.8mm threaded bar glue into the slider part of the print.Slider part is 12mm, I think I used some spare channelling from a LED diffuser.I have included .f3d files, please modify at your leisure, I would ask that you only mod it for your self please and only share the original files.Please do not sell this model. Thank you.
