This was originally a pig model from thingiverse: http://www.thingiverse.com/thing:118121I've retained the same licensing as the original model, to respect the author.There are two bases, or "hot tubs" . one is marked with text, the other is blank.The .ZIP file contains both grouped models (by material type/model group), and individual model files, as well as the Rhino saves. The Rhino Files are surfaces, other than the pig and pig plug, which are meshes, as exported from Zbrush.
