We bought a swing for the garden second hand. It was basically free because two of the seats were broken. Nothing some printing can’t fix. Had to do some CAD:ing and it took two tries but now it’s prestine contditon again.
Of couse, it would have been faster if I didn’t accedently smash the new seat with a hammer when mounting the bolt. You live you learn I guess.
Finally the design is a bit bad. It uses round head square neck bolts (french bolts?) that are only hold from spinning by the plastic, even on the original part. It’s easy to break it here.
