3rd Arm/Hand

2018.04.06 Update:

the all printed link piece works best in xy scaled to 102% so i uploaded Link3_Ring_102.stl
Tipp: thread the ring an the link piece just right to the and to avoid breaking them in joining.

I needed an extra arm for my solder stand
The ones i found were to flimsy so i designed my own.

On all link pieces the strength/stiffness of the joint can be adjustet.
The link pieces can fold 45 or 90 degree (depending on the direction)
