Don't think I ever posted about the wheel spinners on the Bugatti. These are 3D printed and are designed to slip inside the outer edge of a pit bike wheel hub. They are secured by a couple of small cable ties that go through the loops on the back and around a spoke - they're hidden by the spinner. This design is a copy of the Bugatti spinner and in the end I removed the middle to make it easier to access and check the wheel fixings.
I gave them a quick sand, a few coats of primer and top coat.
I'm very happy to share the Fusion360 CAD file or an STL file if anyone would like it.
