45 Degree Razor Blade Plane

thingiverse

To create this tool, my goal was to easily cut 45-degree angles on foamboard edges. Here are the instructions: print, insert razor, and be cautious with your fingers. However, the initial design needs improvement; angled blade placement should be parallel to the cut for smoother results. Currently, it tends to bind and "chew" through foam instead of making a clean cut.
