This is fully flexible moon rover. Rotating wheels, suspensions and quick replacable broken parts.
No supports needed, everything is optimized for printing directly on the bed, but there are couple of bridges. If you are not sure, I suggest to test your printer capability to print bridges with some simple test models, for example Quick bridging test by Aravon.
Have fun - you can place wheel in multiple orientations.
The author marked this model as their own original creation.
