Japanese saw magnetic miter jig for 45° cuts

The model guides saw blades along two sides, which are designed to hold magnets with a diameter of 8mm and 3mm depth. The holes have a tight fit, if it comes to loose, the magnets can also be glued in place. It has a grove which can be used to clamp it to your workpiece and a reference edge. 

Printed on the mini in PETG with 50% infill and without supports. I havent tuned my settings for speed, but I guess most will bei able to print it way faster
