#11 X-Acto Blade Storage
thingiverse
The vacu-formed plastic caddy that came with my X-acto knife set finally died and I was left with an empty lid and nowhere to conveniently store my spare blades. I designed this to fill that void. It fits really nicely in the lid. Alternately, it could also just be printed and left on a workbench or in a tool box. The magnets are plenty strong so you don't have to worry about stray blades falling out. These cavities are designed for #11 X-Acto Blades, but might work with #2 blades also. I haven't tested this, though.
