Models created in Zbrush. They are watertight and ready for printing/milling. Although there are some slight undercuts, they were created with molding and casting in mind.
Version with background inlcudes a highpoly OBJ (around 3.5 Mil polys) and a decimated, optimized STL (1 Mil polys). Version without background includes a 1.5 Mil polygon, triangulated STL and a higher resolution 4.3 Mil OBJ (also triangulated).
