Mechanical Iris

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

very nice work, is there any chance to download the inventor files？

[carlbass]

Let me try and find them

[st155973]

thank you

[patelhiteshr1977]

Thanks a lot

very nice work! thank you so much I almost cried when saw this :')

[NathanE16]

Can you provide dimensions?

[NathanE16]

Never mind. But thanks, this is really cool!

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!

In case anyone is still having trouble opening the files, here are a few more file formats (iges, step, sat, eps, dxf 2010, dxf 2000 .ai cs4, .ai CC )

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

Oops, forgot the .com:

These files are all old windows 1995-2000 files. you will have to download a program

[jpietrzak]

Some of the files wont download or show up as corrupt .tmp files... :/ Help?

[carlbass]

Which files won't download? I can send you any you'd like

[jpietrzak]

The .ipt and .iam parts won't download for me...

[yasmink]

hi, i also cant open .dwfx file and all the.ipt files. can you email them to me? tqvm carl

[bquint]

I have the same problem. Would you send them to me, please?

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!
