screw clamp metric / Schraubenspannklemme (version 2)

Screw clamp for clamping screws in a vise.
With this clamp you can tighten screws in your vise without damaging the thread.
Suitable for shortening or reworking screws with a file or saw.
It is for metrical srews M6, M8, M10 and M12.

I have also added a version made of ABS.

Update (10th April 2025):
I made the original version more stable and I also made a thicker version.
The new standard version is 10mm thick, the new thick version is 40mm thick.
