This is a hubcap for my BBS Nebula 18'' wheels, as someone stole them and I couldn't find any online that were that specific size. It has been fitted on a volvo V50 2006.
The hubcap has a diameter of 64mm for the cap and 5.35mm for the inside clips. Depth of the clips should not be a problem even when mounted on other wheels, or even if it is feel free to change the size in the .ipt file as necessary, just mesure your wheel or a reference hubcap if possible and go for it.
The material I used is PLA, standard settings nothing out of the ordinary and no supports needed if it is printed face down.
On my case, printed on an Artillery Sidewinder 2.

I will be updating the pictures as I will comission an artist for a custom design for the hubcaps, if you want to do the same you can order stickers and put them in the caps, and clear coat over it.
