Comments
A steel ball bearing can roll around in the groove, but it takes three complete circuits of the torus for the ball to get back to its starting point in the groove. The torus was printed in blue, but the groove was a bit too small for the .25" diameter ball bearing. So a dremmil tool was used to enlarge the groove a bit, changing the color in the groove. Color pens were used to mark the groove into three sections.
