HOW TO: Hollow out a model for 3D printing

While looking for a way to save costs on 3D models printed through Shapeway's laser sintering SWF-material type, I came across a very easy to use tutorial that uses the (free) Autodesk Meshmixer.

Essentially, import your .obj or .stl 3D model, Click "Edit" > Hollow. Adjust where the 'holes' are in the model, click the confirmation button in that menu and it automatically generates a second surface between the inside and outside of the model. For some types of 3D printing, this can drastically reduce the cost and time spent printing.
