Floating Centercap (55mm Hub / 65mm Cap)
Print Profile(2)
Description
Designed specifically around my 2022 Golf R, these floating center caps are made to fit a 55mm hub with a 65mm outer cap.
Assembly is simple, and the project can be completed with common hobby materials. For best results, I recommend using 2mm–2.4mm lead balls as ballast to help the cap stay properly oriented while spinning. The heavier the ballast, the better the performance.
They look great right off the printer, but if you want a more premium OEM-style finish, adding an epoxy top coat really makes them stand out.

Assembly
1. Install the Bearing
Press one 608ZZ bearing into each hub.
Sealed bearings are recommended.
2. Add Ballast
Fill the ballast chamber with 2mm lead balls.
I was able to fit about 32g without issue.
3. Fill with Epoxy
Slowly add self-leveling epoxy into the ballast cavity.
Allow it to settle, then continue filling until the lead balls are fully covered, leaving enough room for the cover piece.
4. Install the Cover
Place the cover on top and clamp it down.
Wipe away any excess epoxy before it cures.
5. Let Cure
Allow the epoxy to fully cure before moving on.
Optional Premium Finish
For a smooth, glossy, factory-style look:
- Place the cap face-up on a level surface
- Make sure the area is dust free
- Slowly pour a small amount of epoxy in the center
- Use a toothpick to guide it to the edges
- Remove bubbles with a quick pass from a lighter
Use very light heat — too much can thin the epoxy and cause it to run over the edge.
Let cure completely.
Final Assembly
- Install the cap into the hub
- Apply a small amount of CA glue to the lock
- Use a 10mm flat-bottom screw to secure the lock to the cap
- Install on the vehicle
Now enjoy the finished look and take them for a spin.

Notes
If you print one, I’d love to see your results and which design you chose.
ABS or PETG are recommended.
I was able to use these suction cups to remove the factory caps without removing the wheels. My caps we smooth/glossy so YMMV.
They can also e used to remove the printed caps with epoxy topcoat.
