Mechanical iris

Mechanical iris
===========

Fully functional mechanical iris with 5 blades and smooth operation. Learn how a mechanical iris is working by printing and assembling this iris. No supports are needed to print the parts, but some pins must be glued to the blades. A detailed print and assembly description is available as PDF document.

I also have tried to design a "glueless" iris which still needs no supports for the 3D print. This is possible when the holes in the actuator ring are pins and the blades contain holes. But this is a difficult setup, as the pins in the actuator ring must not exceed the thickness of the blades. The pins tend to slip out of the holes. Therefore the design of this thing is better.

Have fun printing and assembling this interesting item.
