iFixit compatible bit extender

A bit extender compatible with the iFixit Precision Bit Driver. The diameter of the extender shaft is smaller than the one on the driver, allowing for unscrewing of hard to reach screws. Shaft length is resizable in the Fusion source file.

NOTE: this model is very fragile, and not intended for any form of long term use. 

Recommended print settings:

Print vertically with the hexagonal side facing up. No supports. Brim. 100% infill.
Alternatively, you can print it lying down, but the tolerance for the bits is already tight so they may not fit.
