MakerBot and GrabCAD challenge you to design a futuristic vehicle that would exist in the year 2040!

Create your own 2040 vehicle design. How might we travel in the future? Air, Surface, Water, Space. Explore designs that are optimized for 3D printing and can be assembled as beautiful display models.

The second place winner will win a MakerBot Original Replicator (SRP $1,999 USD) and third prize receives $250 USD along with some GrabCAD merchandise.
