Zinc 2.0 More durable PLA Plungerrod

A reinforced version of the original part from 118 Design.
The original is made of aluminum and can easily withstand the load of a strong spring. If it is made of PLA, it breaks after approx. 50-200 cycles, depending on which spring is used.

This version has a higher wall proportion and chamfers and curves which minimize the predetermined breaking points.

After printing, I heated and hardened the push rod on the 3mm axle rod with a lighter for about 5 minutes.

(do not let it get too hot, always turn it a little and maintain a temperature of approx. 80-100 °C)
Afterwards, the material warped and had to be reworked a little with a file.

But now, in the end, it holds what it should without breaking.
