Sphericons

The HexaSphericon, designed by Colin J. Roberts and Paul J. Roberts, can be found on their website at http://www.pjroberts.com/sphericon/index.php. It was successfully printed using a CupCake CNC by Jeff Rutzky, who also uploaded a video of the model in action (http://www.vimeo.com/16985828). To create the rolling path, 3mm rare earth magnets were placed into the two parts, allowing them to be put together in various positions. Models with "Stop" in the filename will stop rolling once hitting a flat spot, while others without "Stop" continue rolling along amusing paths, as shown in the rendering. Chris K. Palmer 3D modeled this unique design, and Jeff Rutzky printed it to commemorate the arrival of his CupCake CNC.
