@Rayp:

There is a free (GPL) tool called Meshlab. Its a lttle more straightforward in the user interface design than Blender because it focuses on mesh manipulation only. It has a megaton of functions build in some of them are VERY useful. I used it for polygon reduction as well as smoothing, repairing, and other transformations. Its really an excellent program. Just in case...

Your monster looks great and 3D prints also (good quality !)
