The file 'Einstein Sculpture (Bust 3D Scan) 3D Printer Model' is (stl) file type, size is 17.8MB.
I found a nice 3D scan of an Einstein bust: http://www.123dapp.com/catch/Einstein/2973574
I used MeshMixer to edit the mesh: I made it solid by filling holes, deleted noise objects, sculpted the mesh a bit and scaled the model up.
