Hoverboard Motor "Tire" for Robots

This is a wheel designed to fit hoverboard hub motors. It replaces the solid rubber tire designed for asphalt with a wheel more suitable for grass / sand / dirt. I plan on using it with a robotic lawnmower project.

It also increases the diameter a little bit which should increase top speed.

I have a wider version of this design here - https://www.thingiverse.com/thing:2959500

Print with 4 perimeters. 20% infill seems adequate.
