Schraubkralle

TL;DR

Tool to hold a screw on top of a bit in two sizes for short and long bits.

Long story

Evolution of a functional 3D model

Saw this and thought i could made much cheaper ones

First version was to brittle for PLA (worked with PETG and TPU)

reddit

Some DIY guys in reddit asked for a small but very cool modification to make it possibly to screw down the screw without breaking the claw. That was the second evolution step.

finally today the 3. evolution

A short version for typical bits and a longer ones for long bits and T-handle bits. The longer one allows you to screw down the screw without the need to remove the tool.

The short one is still best to print in TPU / PETG the longer one can be printed in PLA to without breaking while screwing down to the end.
