We are excited to announce our Gadget Hacking and Accessories contest in Partnership with Shapeways and Popular Mechanics. We have amazing prizes from Shapeways, Ultimaker, and Sphero. The grand prize winner will even be featured in-print in Popular Mechanics!

We also have a special Judges' Prize for entries that uses 3D printing or modeling as part of the build process. EVERY entrant in this contest will receive a $10 printing credit at Shapeways, a special offer for makers to explore the infinite possibilities of 3D printing. You must enter the contest before you receive this credit.

Gadget hacking is modifying, accessorizing, updating gadgets (electronic or otherwise) of any type. Some examples of 3D hacks by the Shapeways community are below.

Ultimaker has posted a forum to answer questions about 3D printing specifically for this contest. Check it out and learn from their community!
