Autodesk and Instructables has announced a new challenge where you could win a Objet 3D printer or many other great prizes. The Make it Real Challenge involves posting an instructable on how to design something on your computer and making it real using 3D printing, laser cutting or decals. An instructable is a step by step post with instructions to show others how to do or make something. You have until April 30th 2012 to enter this fun digital to analog challenge so get busy.
For all the details check out the challenge page:
Also anyone that posts something in the 123D gallery and links to an Instructable could get a nice thank you gift from the Autodesk 123D Team. http://blog.123dapp.com/2012/01/123d-make-it-real-challenge
