Hi, I made this repair kit for a Sprite 1980 Super 1000 caravan (since the ones I bought had too much distance between the holes). But it most likely also fits other Sprite caravans. I recommend printing it in PETG and TPU for the part that grips the ball.

Settings: 0,2 Layer

2 shells in PETG/ABS with 75 infill (stronger)

The insert part in Tpu with 30-45 infill
