Rover wheel for Plum Geek Spirit Rover

I have the lovely Spirit Rover from Plumgeek.

It is very cool, but the little wheels it comes with have very thin treads, and it is not great on carpet.

So I designed some wheels that are designed to fit its motor shaft, that look more "rover like".

I tested these, and they provide a marginal improvement in performance on carpet. I may modify the design to improve the amount of contact surface, and add a groove for an o-ring, which will make movement on hard floors quieter and more effective

One version is left & right mirrors for FDM printers (filament extrusion), and the other version is powder bed or self-supporting printers like SLS or HP MJF.
