3D print center caps for VW Beetle "American Eagle" 8-spoke wheels. Might fit others with scaling. Designed with both solid centering lugs and snap-tabs, though the snap tabs broke off, I used hot glue to hold it in. Lower profile than the originals so they wouldn't hit the ground if I lay the tire on the floor face-down, but still clear the axle nut/bearing cap.

Designed this quite a few years ago, no longer have access to the CAD to modify the files.
