Caravan door retaining strap - Wohnwagen Tuerfangband Knaus Eifelland

Print in ABS or similar strong material with some flexibility (PLA will not work). Print using a raft.

If the ball will not snap into the joint due to tolerances of the print, just sand down the joint (not the ball) a little (not too much or the ball will not hold anymore).

I added the ball joint because all tries to replicate the original failed due to early snapping of the strap.
