Compact Screwdriver

This is a compact screwdriver that holds 6 standard 6mm hex bits in the handle and a standard bit extension in the middle. The whole thing folds away for compact storage.

Depending on the tolerances of your printer, the actual diameters of the hex bits and the bit extension can be modified in the Fusion 360 file that you can download if necessary. To change the parameters in an easy to use table, go into Modify > Change Parameters.
