Because I lost my plastic hubcap while driving. I decided to fix these caps with an M10 bolt. But before there was a sticker on it that had to come off now. That's why I decided to make a plastic cap so that the bolt is out of sight. (This is a 2cv kit car where it is a chassis of a 2cv6) I made it in Tinkercad and printed it out in PLA. If I lose it you can easily print a new one.
