Introduction: Mechanical Iris

About: self-unemployed maker
I've seen lots of variations on the mechanical iris but not many plans for one. My 13 year old son and I worked on this together to figure out how it works and how to make one. We built several variations in different materials using slightly different fasteners. Several were laser cut and one was 3D printed. I've included drawings and models so people can easily modify it and make it better

And here are a couple videos showing it in action

And here's a visualization of it

Here is the Inventor model
