KeyRing Screwdriver 5/32" bit holder
A simple bit holder for 5/32" screwdriver bits. It is designed for 19,5 m long shaft hexagonal bits but you can customize the design for other sizes as I am providing de sketchup source file (scale 100:1) as long as the stl files. You will need 2 tiny screws (I used märklin 1.6x13mm, p/n 74990) but any similar screw will do.
