Miter Box 4

Remix of orginal, the slots are set up for 90 degree, 45 degree for both left and right cuts. You can alter the number, placement, and size of the saw slots, as well as the size of the overall box all by editing the parameters. I have this one set for 30mm maximum stock, but you can easily alter it (just open the file in OpenSCAD and go at it)
Note: The placement of the slots versus reinforcing bosses on the
slots is NOT automatic; you will want to wiggle them a bit to make them look nice.
Print it in PLA or T-Glase, to get maximum rigidity.
