Eyebrow/Mustache Safety Razor

I was getting tired of buying eyebrow razors to shape up my mustache when I already have plenty of blades for my safety razor. Just fold them in half to break one and slide them in! A simple cover for the blade is also included -- if you make something a bit fancier than a box then please feel free to share! :)

Depending on printer tolerances and slicing options, you may need to use a small knife (or something similar) to open up the bottom hole in the back for securing the razor a bit better than friction can do alone. I've also found myself occasionally needing to run the blade through the front slit where the razor's edge is exposed prior to sliding it in. Your mileage may vary. Try to be safe!
