Modular system screw-bit and drill bit holder

I got tired of having to go searching for screw-bits for my Makita battery powered drill, which I have on my wall via another 3D print!
So I made this piece for my modular system that holds two screw bits. It can also hold an undersized (skinny bit) or a commonly used drill bit in the third hole.
I added a small little shelf so the drill bit won't fall on the ground.

Enjoy. I have been using my 3D printable modular tool system for ~7 years now.
