I bought this set of X-Acto knives:

I wanted a way to store them where I could grab them quickly to trim something/make a couple of cuts and put them away again quickly. The tips are protected to both keep them sharp and stop you from getting cut.

Also pictured and NOT designed by me:

P.S. you need to be careful about how you orient this when printing it. If the "blade grooves" get filled in with support, it is extremely difficult to remove the material.

Enjoy!
