About this 3D model

Some weeks ago i found chris schaie's [1] iris on hackaday [2] and i was so amazed that i took a screenshot from the video and made my own iris based upon his design. From there it was a long road but eventually my own design worked out and i managed to create a mechanical iris that can be opened with a stepper motor. Now we have a welcoming system at the metalab [3] [1] http://schaie.com [2] http://hackaday.com [3] http://metalab.at
