The Marmot - 1:10 scale off-road buggy

Ah, nice marmot! The Marmot is a bathtub-chassis, rear wheel driven, vintage-looking buggy with special features such as rack and pinion steering and funny rear suspension.

Printing should be fairly straightforward, but some parts will require supports. I recommend sanding and painting the body, wing and roof.
