Prepping for Printing: From 3D Warehouse to 3D Printer

Don’t you just hate it when you download a sweet looking model from 3D Warehouse and your plans to print it out on your 3D printer are thwarted when you find that the model is not a solid? What do you do when you need to get an extruded PLA copy of the Burj Al Arab Jumeirah Hotel in Dubai, and you need it now? 

Don’t panic! Fortunately, I needed a printable scaled version of the US Capitol Building, and recorded the process of transforming the unprintable into a manifold solid (manifold is a fancy term for a solid group)!
