Introduction: Iris Business Card
This is an iris mechanism built into a business card sized card.
The design files can be downloaded here: http://www.thingiverse.com/thing:8787
Another version with 4 leafs: http://www.thingiverse.com/thing:8944
The paper needs to be fairly thick because it needs some stiffness to operate. I use a 14 point (0.014") paper
It can be cut by hand, but it would of course be much easier on a laser or paper cutting machine.

Do you have a template for printing the card info?

Sorry I don't have a template specifically designed for easily adding text to this one.
If you want to add text on it I would suggest working with the .svg file with the free vector program "Inkscape".

Is Inkscape available for Mac?

Thanks for posting that. That one even pre-dates mine. I tried searching around to see if anyone had ever done it before, but that didn't show up in my search.

cutting this by hand is a real pain, but is still really cool. if i could someday make it out of metal then it would slide much easier, since i could file it and add grease and stuff. nice job!

I was just wondering about a snap -back-in-place version where the iris would snap back into the closed position.

Well it works to a limited extent just to make some notches on the body and arm and put a rubber band around it, but it is really touchy about the tension. Too much and the card will start flexing too much when you try to open it and too little and it won't close by itself. With some work you may be able to incorporate something internally, but I haven't had much luck putting rubber bands inside something this thin.

im toying with the idea of using thin metal like aluminium can. even thought of vary thin rare earth magnates glued but that kinda defeats the use of paper.

I don't know how well magnets would work because of the distance it has to travel. Maybe a large diameter but relatively weak torsion spring could work, but you would probably have to make your own because I don't think I've seen one that size.

sorry, but isnt this a copy of the portal two business card instructable. im not beeing mean but idk if this is just a different version or what... it sure looks like it. but you did do a great job

I posted the design files for this back in May on Thingiverse. drknotter modified my design (quite well) to make the Portal 2 business card. I was just late getting this video posted here.

I just made one!
closing works pretty good but opening is a little bit difficult,
but that's probably because i've cut it out by hand and som edges are a little bit rough
but I like the instructable :D

I made this video back when I first made the card and kept forgetting to post it here.
I do have one more card design coming that is my simplest so far and quite fun, but it may be a couple months before it is ready.
