This is inspired by the Chilean tradition of giving ceramic (or in this case, plastic) pigs to friends to bestow good luck.

The pigs typically have 3 legs because it's fast and easy to sculpt clay that way. Even though I can make 4 stable legs for this 3D printable version, I chose to stay true to the original.

I haven't had time to paint it yet.

Take a look at your g-code preview before you start. If you see support columns appearing in the nose or eyes, you should either reduce the threshhold angle, or turn support material off entirely.

Supports will help keep the belly in shape directly underneath, but if you have to print without it, the errors should be well hidden since they're on the bottom between the legs.
