The device breaks too fast - and the plastic:
a) in the field of zinc bracket (with metal studs mounted) and b) of the ejector.
I built a long metal bolt in order to get more contact surface on the plastic (after the plastic was already out). This then has not kept but long. If the metal bolt with 6mm diameter is bent (as you can see what kind of forces), the original bolts are probably cured, but too short, therefore breaks m. E. the sculpture made in the field of zinc storage.
