Summary

Diameter reducer insert to use 50ml centrifuge tube (dia. 29mm) on larger bucket (63mm).

Inner and outer rims are 3mm thick. Spokes are 2mm thick.

Printed in semi-flexible TPU (Ninjatek Cheetah) to absorb more efficiently any possible vibration.

Designed with freecad.

Note: It was a first attempt. Design could safely be updated with thinner rims and fewer spokes to reduce overall weight as the current design seems quite sturdy.
