As the piston on my shock absorbers was broken and I didn't want to order online because of a component costing a few cents, I designed the piston. Printed in PLA, diameter 10.89mm. The installation is done simply by replacing the old one.

There are 3 versions available, with 2-4 holes so that the oil can flow through. The less holes the harder the oil goes through the holes so the harder the damper.
