Expect updates to this thing! I will also upload a STEP file for easier editing! These are the OpenRC car shocks for 1:10 RC car. I have replaced all my original shocks and will continue develop these. Consider it a proof of concept and experimental though. Hardness of the spring can be adjusted by adding/removing "rings" or change the shape of them. Spring needs to be printed in Nylon to work! 1 pcs 50mm M3 screw needed and two smaller ones to keep the "lid" in place.
