For those who want to win Cube 3D printers, here is another opportunity for all of you. Cubify has launched Summer Sunglass Design Challenge which will be open from 2nd July. 2013 to 31st August, 2013.
If you want to participate in this challenge, you will have to send the entries in form of STL files. To create your design on Cubify, you can use either the party or the plain glasses template. These both templates can be used in a .FUN Cubify Invent file. These entries can be submitted to the Cubify till 31st of August, 2013.
You need to make your designs printable on Cubify or submit them in such a way that they could be printed with Cloud Printing material like Cubify Everlast or Cubify Acutough. Do not forget to read the rules before that though they are pretty simple and give participants with lots of possibilities. The winner of this competition will be awarded with a Cube 3D printer.
