Shaving razor box cutter

Ever wish all those waste blades after shaving could be used for something else?This box cutter is made made to fit double edge safety razor blades. (The ones you shave with). Has versions with or without keyring.I had to print the wingnuts at 110% width to fit on the threads, I don't have your printer, but you might have to do the same (thankfully they print very quick). I would probably recommend printing the parts with threads at 0.1 layer height.Adjust the wingnuts to change the sliding resistance.If you want more blade length you can scale the base piece longer. I mostly made this thing to learn CAD.Use at your own risk, I'm not responsible for cutting yourself.
