The Raspberry Pi Foundation, Autodesk 123D and i.materialise have teamed up to sponsor a Raspberry Pi Case challenge. If you can design a 3D printable Raspberry Pi case you can win your own Raspberry Pi, an Autodesk Premium Membership and other goodies.

This design challenge is a lot like a Highlander competition; you can enter as many times as you like but in the end, there can be only one winner. A panel of judges from the Raspberry Pi Foundation, Autodesk 123D and i.materialise will select the winning entry.

The challenge is open to everyone, professionals and amateurs alike, but there are a few rules you'll need to follow when you submit your entry. First, your case design must be printable in Polyamide. You don't need to print the piece yourself, just upload your files to this page. You will also need to include a fifty word description of your project when you submit it.

The size limit for submitted designs is 15 x 10 x 10 cm and your entry must be an original creation that has never before been 3D printed. Contestants are welcome to use any design software they like including Tinkercad and Autodesk 123D, but all entries have to be submitted in STL format. The contest ends at 23:59 Central European Time, September 1st, 2013.
