Allen Key Holder

I wanted a nice Allen Key holder to replace the plastic pouch I had. I was inspired by the Allen Key holder by Useless_Heatsink but I wanted to design it myself and fit a cover over it.

The cover is held on by M3 x 40 Long screws and nuts. My printer is a single colour type and I made it so that the numbers can be inserted and glued in place. A cover encloses the aperture.
