Recently i bought these rays evo 3 wheels, and they didnt have the center caps. Searched online for quite a bit, turns out the original ones are practically unobtanium and are stupid expensive. So i found a model online for it then printed it lol next im gonna have to design and print a socket adapter to tighten the printed nut down too so it sits flush.

It's printed using eSun ABS MAX so it can handle the heat just fine.
