This screwdriver is designed to allow the use of any standard bit in otherwise impossible to reach places.

Additionally, it has an adjustable handle allowing you to change the tool's overall length, providing extra reach and more leverage if needed.

The end effectively adds only 0.5 mm to the height of the bit and 2.6 mm to its width.

This design comes with two screwdriver models:

• the first includes an insertion slot for a commonly available 8 x 3 mm neodymium disc magnet, and
• the second is built without the insertion slot for a magnet.

While using the magnet is optional, its use helps to hold a metal screw in place on the end of a metal bit.

As desired the bit may be stored in the handle; the handle fits both of the models above. 

Included are the all the associated .stl, PRUSA, GCODE and Fusion 360 source files.

The PRUSA and GCODE files for the model for use with a magnet have an automatic pause point in the print allowing you to insert the magnet at just the right point in the printing process.

Both screwdrivers models print without the need for supports, the handle prints best with a brim.
