3D Printed Boxcutter

A few years ago, I was playing with one of my dad's knives and figured I could make something like it, but using boxcutter blades. I looked around on Thingiverse and Printables but didn't find anything like what I was looking for, so I made my own. It took a lot of trial and error as well as two complete redesigns, but the Gen 3 versions work fairly consistently and have a few other tools built in.

The models and CAD files can be found here.
