Made some modifications to suit my lawnmower project. Ive included the file I use to subtract the wheel/motor shape in my slicer (negative volume in Prusaslicer) Its easier for me to do it this way as I can manipulate the size/shape of the tyre without changing how it fits onto the wheel.

IMPORTANT! this file WILL NOT fit onto a hoverboard motor/wheel if printed as is , you NEED to combine the two in your slicer

The HBwheel file is Based on measurements taken from MY Hoverboard motors , Although Ive noticed quite a bit of variation between different models so you may want to double check or just model your own.

Thanks to AmpEater for making the original File and saving me a load of work.
