A friend of mine wanted me to print the source Cthulhu scan
(http://www.123dapp.com/catch/Cthulhu-YSDC/2933349), but as you can tell, it's missing the top and bottom parts. I thought that was the end of it, but I found meshmixer and started learning how to use the program. This is the result, which is my first attempt at customizing a 3D model. Please feel free to modify the model and make it even better!
Update 1 (2/5/15) -
I went back to Meshmixer and removed the inner shell so the model should print solid now.
