Mechanical Iris
grabcad
The mechanical iris mechanism comprises 12 leaves, as suggested in the design; however, I couldn't manage to include all of them. If anyone can accomplish this, feel free to do so. The idea was derived from Instructables.com, and I must give credit to "kommodore" for sharing the tutorial on making a 12-leaf mechanical iris at http://www.instructables.com/id/How-to-make-a-12-leaves-Mechanical-Irirs/?ALLSTEPS.
