Cubify has announced the launch of their Summer Sunglass Design Challenge and Party Glasses App. The Party Glasses App allows you to customize sunglass templates with your name and then pay $9.99 to download the resulting STL file. The Summer Sunglass Design Challenge snags the winner a free Cube 3D printer.

Summer Sunglass Design Challenge contestants are invited to submit their 3D-printable sunglass designs to Cubify via this page and the Cubify community will vote on the submissions. After a period of community vetting, the highest-rated sunglass designs will be chosen as finalists.

The selected pool of finalists will be evaluated by a group of Cubify's featured artists and they will choose one winning entry. The winner gets their own Cube 3D Printer.

You can use any software you like (including the Party Glasses App) to create your design, but the submitted file must be in STL format.

The Summer Sunglass Design Challenge ends at 12pm EST on August 31, 2013. Only one entry is allowed per person, so choose your submission carefully. The grand prize winner of the contest will be notified on September 14, 2013.  You can view the official contest rules here or upload your STL file here.
