SummaryThe 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: Can the models be printed on the majority of consumer FDM printers? -Bonus Category: Description of design process, the models and/or tornado info. Prize: 3D Design Champion card. Physical card mailed within US. Digital card for international winners. Designs received before 4/30/21014 and linked as a remix of this thing will be considered. More info about the origins of this challenge and the designs from a 2013 STEM camp can be found at http://designmaketeach.com/2014/04/14/fujita-scale-3d-design-challenge/ Original Tinkercad models: https://tinkercad.com/things/3JHoOWTLGye, https://tinkercad.com/things/6kU0cGT6lyH, https://tinkercad.com/things/gbTjfEmgltn, https://tinkercad.com/things/d1h35EWYjz4, https://tinkercad.com/things/4kWdsjxHrF4 Please leave a comment or contact me on Twitter @DesignMakeTeach or on Facebook at Facebook.com/DesignMakeTeach. I love to talk with teachers, designers and makers about 3D printing, STEM and Learning by Making.
