A 123D Catch Scan captured from the Museum of Natural History, cleaned up and print ready.
"A plaster reproduction of one of the largest and most impressive Olmec stone heads found in Southern Vera Cruz and Tabasco. On display in the Hall of Mexico and Central America."

(oops, I've misspelled Olmec in all my file names - but I'm not uploading them again just to change it!)
This catch turned out great. All photos stitched automatically and the program generated a nearly flawless mesh of the face. I used mesh mixer to extrude the side faces further back. I transferred the file into blender where I did minimal enhancement of creases and a touch of smoothing. A boolean to create a flat back, and add a base for easier printing, and it was good to go.
I think this made an easy catch because:
1. Despite the very dark lighting, the shadows emphasized geometry and didn't obscure anything important.
2. This sculpture is in a relatively quiet corner of the museum. I was able to get shots without a lot of visitors in frame, and could easily pause when kids ran into my shots for their photo ops.
3. Simple and well defined features
4. I had just over 180 degrees of shooting range, as well as low and high shots for a lot of variety.
5. I shot this with my iPhone after I'd used up the SD card in my camera earlier in the day. You'd don't always need a good camera to get good results.
OlemicHead.stl - Ready for printing, with it's back oriented on the platform
OelmicHeadwBase.stl - Ready for printing in a vertical orientation with a base to simulate the one at the museum.
OlemicScan.obj - Somewhat cleaned up scan data. Not manifold, but good source material.
