We’ve been watching the work of RoboGenius for quite some time. He has created some of the neatest non-geometric work anybody has done on the Egg-Bot. Recently, he uploaded a number of his designs to thingiverse, which means you can try them out, too.

The Original Egg-Bot! – Deluxe Kit! – The Eggbot is an open-source art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball to that of a small grapefruit– roughly 1.25 to 4.25 inches in diameter (3 – 10 cm). The Eggbot is super adjustable, and is designed to draw on all kinds of things that are normally “impossible” to print on.
