We're excited and proud to launch Thingiverse Apps. Learn More about what this means to you.
Some weeks ago i found chris schaie's  iris on hackaday  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
