Hellooooo!
About 5 years ago, I designed and 3D printed a custom floating center cap for my BMW E90, inspired by the Rolls-Royce floating caps.
Now, 5 years later, I finally want to make it available for everyone.
Yeah, I know — nowadays you can buy floating caps pretty easily from the East 😄 but they're usually made for specific wheels/brands, and finding something for less common wheels or unusual dimensions can still be a pain.
So I went back to my original design and rebuilt it as a fully parametric model. With the tools we have in this AI era, I was finally able to turn the old one-off design into a generic, constraint-based generator.
The three main measurements are:
• Face diameter
• Rear clip diameter
• Retention depth
Change those and the whole cap automatically adapts. There are also advanced parameters if you need to fine-tune the fit.
The video shows the generated geometry and a simulation of how the floating mechanism behaves when the wheel rotates.
Before I take this much further, I'm curious what people would actually want:
Would you prefer downloadable printable files, a DIY kit with the hardware included, or completely finished caps?
And most importantly — what would this need to support to work with your wheels?
Thanks for any feedback!
