Mat Knife (with blade storage drawer)

thingiverse

I teach a projection mapping class. As part of the class the students build models of venues out of foam core and poster board. I need a mat knife to bevel the foam core as part of the construction process. Didn't fee like purchasing a separate mat knife with another type of blade since I already have dozens of x-acto blade handles, and hundreds of spare blades. The blade should make a cut at 1cm from the edge of the holder, so bear that in mind when using.
