In this Instructable, I'll step through how to make a 7' tall statue of liberty bust out of cardboard using Autodesk's 123D Make. The inspiration for this project was the last scene from *SPOILER ALERT* Planet of the Apes.

Autodesk 3ds Max (alternately you can use a free software like meshmixer)
p.s. I built it at TechShop!
Step 1: Secure a 3D model
You can find 3D models online on various websites like turbosquid.com
You can also 3D scan a souvenir statue.
