HPI Ken Block WR8
Shock part from #101212 for the springs
I have no idea what to name this, but it's a spare part from the "#101212 Shock Parts Set" for the HPI WR8 and Bullet. It doesn't look exactly the same, but the measurements are good enough and it's printer-friendly.
I've included a file with custom made supports.
Hope you like it!
