Mars 2020 5 inch wheel

A scale wheel from Perseverance, cleats and all.

The actual model file, as it will be printed. Drag to turn it.

Perseverance rolls on aluminium wheels with curved titanium spokes and gripping cleats — redesigned after Curiosity's were punctured by sharp Martian rock.

Published by NASA in their 3D Resources collection, which they state is free of copyright. Printed to order — scaled to about 80 mm on its longest side, and resizeable on the next page.
