This is a fully printable third hand to help with soldering small parts or to hold something still while you work on it with your two other hands.

The clip has to be printed with supports for the part that attaches to the “snake”.

You can adjust the stiffness of the links by adjusting the link_tolerance variable in the scad file. The more negative the number is, the tighter the fit will be.

I print it at 0.3mm layer height and it works perfectly.
