Fujita Scale: 3D Design Challenge

The Fujita Scale 3D Design Challenge is to create a series of 3D printable models that illustrate the categories of tornado damage from F0-F5. http://en.wikipedia.org/wiki/Fujita_scale

Entries will be judged on 3 Criteria:
-Accuracy: Do the models accurately represent the Fujita Scale categories? ie. Would the majority of meteorologists or engineers in the field agree with the classifications?

-Realism: Do the models show realistic man made structures and vegetation?

-Printability: C
