This is a tutorial on how to manually hollow out and make your 3D model have a shell. "Shelling" before printing can greatly reduce the amount of material you need for a 3D print. It also can greatly reduce the amount of stress you put on the printer. In part 2, we will cover adding additional supports to the inside of the model with Zbrush Z-Spheres. Whenever we make new surfaces, we also have to make sure they are properly supported!
Special thanks to Giovanni Nakpil for lending us his awesome model to use for this tutorial.
