I opened google sketch up and used the feet and inches template. I made a circle, and raised it. I did the same for the eyes, nose, and the ears too. I then had to scale down the pig and and the main circle was around three inches. After I was done, I selected the whole thing. I then clicked tools and pressed export to DXL or STL. I then exported it to millimeters, and made it a polyface mesh. I saved it to my H drive, and then printed it to the makerbot.
For the makerbot, all I had to do was preheat it and print it.
