This is a model for Makerbot's new experimental dualextrusion. It was designed by Elliot Cohen (ecohen) , Jon Monaghan (JonMonaghan), and Michael Curry (skimbal). It is a two color world in fabulous 3D! Once equipped with a Thingomatic armed with experimental Dual MK7s one can print the earth in two different colors. In order to generate a dualextrusion gcode, load up the newest experimental-dualextrusion supporting version of ReplicatorG, select the "Dual Extrusion" menu under the Gcode dropdown and merge your two stls.
