Two Circle Roller - Oloid-like shape

thingiverse

This is a type of shape referred to as a "two circle roller." It's a mathematical shape that, when it rolls, every point on its surface comes into contact with the ground. In any case, Wikipedia does an even better job of explaining it... https://en.wikipedia.org/wiki/Oloid Print TWO halves and then glue them together. An openSCAD file is also included if you want to experiment further. Not my video, but a nice animation of how this shape rolls: https://www.youtube.com/watch?v=GUyou2QelRo **Edit:** My father-in-law corrected me that this shape is not an oloid. He was technically correct. The two-circle roller is a shape only associated with the oloid. This author deeply regrets the mistake.
