Lego compatible Shock Absorber V1.1

This is my shock absorber for Lego Technic models.
This Version has two axle holes instead of the normal Lego Pin Holes.
Other Version can be found here : https://www.thingiverse.com/thing:3147718
I chose a spring with 24mm normal length and 11,5mm travel.
After Printing you probably have to drill the holes to make them exactly.
On the side with the spring, drill the hole with a 2mm drillbit.
Then insert a steelrod with a diameter of 1,5mm on the other side.
