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

Any chance you've made one with 8 blades? I've been scouring the web to find the calculations needed in designing this but have come up with none.Thanks!

http://iris-calculator.com helps you create your own iris. It's been a very helpful resource for me.

Just wanted to say thanks for posting native IV files :)
Those of us who are do use Inventor really appreciate not having to create feature trees from some imported unintelligent format.

anyone meander a guess at why these inventor files seem to download only as garblenamed .tmp's on my end? pardon my grocer's apostrophe. they appear to be similar in size.. might they only require re-naming to the proper file extension? no harm in tryi...ahHHHHH!

When I first saw this it reminded me of a "Longworth" chuck that I made a while back. I'm pretty sure this could be made into a "steady rest" for use on a wood lathe. It would need a little modification, especially a way to lock it in place after adjusting and also adding a base so it can be mounted on the ways. Thanks for the ideas. Now all I need is a laser cutter and learning how to use it!
