This ornament was based off of a true ferret. My ferret. His name is "Hobbs".
I built this using 123dSculpt - an iPad application where you use your finger to mold the model. It's pretty difficult to get decent detail, but it was fun and a good experience.
I then pulled it into Rhino 3d to split it in half and zero out the feet.
The model is split into two pieces so you can print it without any support material. Simply print the top, and then the bottom, then glue them together.
Alternatively, you can print the whole thing if you want to try with support material.
