After successfully printing a Konoid I realized I just tapped into a very interesting new (for me) area of extremely simple and amazing mechanisms.

One can argue that a mechanism must have at least two parts, and a roller by definition has just one - itself.

Nevertheless, there is a second part to the whole picture - the surface it's rolling on.

And the idea is to always keep the center of gravity at the same distance from the surface no matter what position the roller is.

Sphericon is the best theoretical source for these rollers, so I decided to pay it a tribute and produce a 'see through' version of it.

This is how OctoRoller Classic came to life:
This picture is a cross-eye stereopair.

It printed well in polished bronze.

It rolls great and produces the AWE effect very well.

I am sure it'll look and roll great in other materials.

I made it available in five sizes - Check out my shop, GeoMachine

Get one and get amazed!
