A 3D scan and print of a shell that my wife and I found on the beach while on vacation a few years back. This is my first attempt at 3D scanning. Scanned using David3 software with a structured light setup. The shell was laid with the opening facing down on a turntable and rotated. I didn't try to scan the bottom, so the software just made its best guess at what the bottom should look like. Obviously, there is not good printing surface on this, so you're going to need full support or to slice it in half and glue together.  I've attached a full resolution version and a reduced res version.
