I made a small bit holder screwdriver to hold leatherman bits. The back end is free spinning and can be removed to acces the bit storage part.

It stores 2 bits inside. (i placed a small piece of foam inside to stop it from ratling around)

I tweaked the fitment of the bit holder mechanism a bunch, if there are any problems let me know and i will make adjustment.

(i also have a version without the unscrewable end if someone is interested let me know :) )
