Treaded Onewheel Fender for Plus and XR

This is a 2 piece convertible fender with a motorcycle tire styled tread pattern. The top is removable. There are recesses on each side where the top and base meet for a 5/16" diameter x .118" thick rare earth magnet.8 in total. Although it does hold well enough to not need them. 

The base is printable without supports but will require a 310mm x 310mm bed size to print.. The top however will need them since it sits on the 4 corners of the dome shape. I set the support overhang angle to 5 degrees to generate support under the entire piece. It's recommended to use ABS or some other high temp resistant filament but anything will really work.
