This is a remix of schutz's Pocket Screwdriver Kit. This kit holds ten of the flat Leatherman driver bits.  They fit well in the elastic loops on the side of my nylon Leatherman sheath. 

I added extrusions for six 5mm x 1mm disc magnets to add retention for the bits if your print tolerances are loose. There are also extrusions in the bit slot for 3mm x 1mm disc magnets, but my prints were tight enough to not require them.
