Wheel Center Cap Adapter for 64 mm Mazda RX-7 FD to fit in 57 mm later model Mazda OE wheel caps.
Newer versions maybe posted later where the smaller cap is seated flush.
Use the Support version file if your printer has a hard time printing the gap in the wheel cap.

Flat top version has supports for the sides but you must slice it with support before printing or print upside down.
