This a 3D scanned model of a (probably) Mayan sculpture. I found it at 123D Catch models, there wasn't much info but I guess it's from the Advanced Visualization Center from the University of South Florida. They have Maya 3D scans for students, pretty cool right?
I used MeshMixer again to plane cut the surroundings and making a flat bottom surface for 3D printing and I scaled it up to 125 mm in height.
There is an STL file and also a color model (zipped).
The original scan is here: http://www.123dapp.com/catch/USF-Museum-Visualizations/3382857
The author marked this model as their own original creation. Imported from Thingiverse.
