Garmin Varia d-shaped Seatpost Adapter-insert for Cervelo Caledonia 5

I have a Cervelo Caledonia 5 (d-shaped seat post) and the offical Garmin Varia quarter turn seatpost mount. This design replaces the rubber insert on the inside of the seatpost mount to better fit the d-shaped seatpost mount of the Caledonia 5. It may work on other d-shaped seatposts. Still has some gaps but is definitely a better than the original.

Printed with TPU. Just cut after printing to fit around the varia mount.
