Ever since I saw 'The Lorax' I have loved the idea of a mono scooter. A single wheeled gyroscopically stabilised ride-about. So here is my version of the mono-scooter.
Started with the tyre which is a simple circle extruded along the path of another circle, at right angles to the original. The tread was created by extruding every other single surface in one row, creating a mirror of that in the x axis and then duplicating and revolving, repeating the duplication and revolving steps until the whole tyre is completed.
