This is a single head taken from Rebel's Easter Island Moai Statues http://goo.gl/namKU found on Google's 3D Warehouse as a simple test for exporting STLs from Sketchup and processing models in Netfabb Cloud. The object has been printed on a Cupcake with Sanguinololu running Sprinter/Printrun/SFACT.Print using external support material to support the chin and give it 4 or 5 solid layers to best fill the top of his head.
