The old Mr. Satan was scanned in 3D and converted into a file for the CNC machine to create a new Mr. Satan from a 300 lb block of solid steel. It serves as a furnace with fire blowing out the eyes, nose, and mouth and can be attached to various machines (like the Bombloader). It made it's debut at the 2007 Maker Faire in San Mateo where Mark 'blessed' it by spitting on the already red-hot face where it instantly sizzled into steam. Unveiling of the new Mr. Satan
