About this 3D model
This thing has moved to Youmagine https://www.youmagine.com/users/jensa so I don't also get sued by Stratasys... Wanted to make a LED-cube so I made this model of a 5x5 cube in Rhino. You can read about the project here: http://flashgamer.com/arduino/comments/making-a-blinkenlights-cube
