Bevel cutters

Holders for 9mm snap-off blades from utility knifes to cut foam sheets at a certain angle. Made for 45°, 30°, and 22.5°.

In the larger versions, the retracted blades don't protrude at the other side.

You need to add an M4 screw with a maximum length of 15mm (I used 10mm), a washer with 12mm outer diameter (4.5mm inner diameter and 1mm thickness) and a 9mm snap-off blade.
Put the blade into the slot and adjust the protruding length, then insert the screw with the washer and tighten. The front edge of the tool can be used to guide it at a ruler.
