If you can design a 3D toy, you have the chance to win a fully-assembled Ultimaker 3D printer and a six month supply of PLA. Ultimaker put out the call for submissions yesterday, announcing that they want you to, "be creative and have fun creating your design!  Basically toy around with your thoughts, put them into CAD form, and then submit."

They're going to be accepting entries until June 5, 2013.  Ultimaker isn't looking for the physical toy here, just the completed design. To enter, you'll need to submit your ideas in IGES or STEP format and upload them to the GrabCAD library via this page.  Mark them with the tag "Ultimaker".

The rules are simple:

  1. You can enter more than once
  2. Work alone, or as part of a team
  3. Your submission must be 3D printable
  4. Bolts, screws, glue and snap assembly designs are allowed
  5. Unassembled parts should be no bigger than 21 x 21 x 21 cm.
  6. Submit your own original work, and avoid submitting anything that has a trademark or copyright in place (Sorry, no 3D Stormtroopers allowed)

Your submission is going to be judged by a panel of representatives from Ultimaker, Ground3D, Protospace, and GrabCAD.  There will also be several guest judges including TCT Mag's Jim Woodcock, and PCMag's Dan Costa.

So what do you get if you win?  Along with bragging rights and the happy glow of recognition, first prize wins a fully assembled Ultimaker Printer and a six month supply of PLA.

If you've got your eye on that Ultimaker 3D printer, rest assured that you don't even have to come in first to win it.  If you place as high as fifth, you'll still get an Ultimaker and Ulticontroller combo kit.  That's essentially the complete 3D printer, with some assembly required.

Your entry will be judged on its overall coolness and creativity, along with whether or not it can be printed in 3D.  You can check out the complete contest guidelines here.
