A mini ratcheting screwdriver build around a standart (Bosch) Bit extender, which is therefore pretty sturdy and allows ergonomic small space handling! 

Works with PLA but use preferably PETG and ABS.

If there is enough interest I might make a bigger version too! :)

Features

• Rachets while screwing in (and out as in different Versions)

• * A wheel to grab for locking the driver (better print both versions to use one driver for tightening and one for loosening)

• As small as possible while accomodating the bit extender as a sturdy core piece

• A ergonomic compact handle design to reach into small spaces

• Fits almost any commen drill bit

• Adjustable: Depending how deep you pressfit the Bit extender you can adjust the drivers length and shape (~20mm length increase possible if needed)

• Adaptive: Also through the rachet it can freely rotate in one direction but not in the other direction. (But you can stop that by gripping the wheel)

You need: A most standart bit extenders from most drills work!

Printing Orientation

• print with no supports and the rachet facing down

• Use a brim if needed but only on the outside!

Press the Bitextender in from the front. This extender is securely held in by friction!

I Hope you like it!

Happy printing!
