About this 3D model

Inspired by this guy and his low melt metal molds, http://www.thingiverse.com/thing:26500 and some to this guy for starting me on the coding http://www.thingiverse.com/thing:31581 and this guy, for taking it to the next level (HiTemp-LostPLA) http://www.thingiverse.com/thing:82176 I chose Clive because he has a ton of detail...and is cool. I realize some more of the mold could have been cut away...this stuff is not easy I'm not sure if the walls are thick enough for the heat, and I still want to make a shell (hollow instead of solid) But I wanted to get something simple(ish) to go with my print of his shell mold when I pour in next day or so. From the shape of this mold, it can pretty much only be used for Lost PLA. I am doing several more ver of this before I pour, at least one of them will be useful for other types of molds.
