I had some problems printing the Iris Door Box work with those tiny potrusions of plastic acting as guides (they just kept breaking), so I made a derivative with holes and M3 screws and bolts that uses the bottom of the hole as the guide.

Only the box is modified, not the leaves nor the ring. Indeed the box looks just the same from the outside (except the bottom that has extra holes and extra screws :p)

Thank you, countspatula, for making such an awesome yet simple box, I've always wanted to have one!

All the credit to countspatula!


You will need the 3 STL objects in this thing (I only made the modified version of the small short iris door box) and 5 conical head 10mm M3 screws (or some like those, I used some old computer screws), and 5 M3 20mm screws with 5 M3 nuts that should be put inside the holes.

If the M3 nuts do not fit by pressing, use a soldering iron to press them, but be sure not to touch them afterwards, I've been burnt to many times by doing that (I'm reckless lol).

Had to print @ 104% to make the 10mm m3 to fit, and ended up using some even smaller screws for the 20mm... but it works!

I have a laser cutter and would like to have a go at making it in layers of acrylic. Do you have any plan views, pdf or dxf files you can upload for me?
Thanks, Bondy

I'm sorry for the late response, I got this from another thing (see the derived section above). I barelly got the STL and modified it a bit to add the screws :S

You may be able to get something out of the STL though, But they are mostly complex pieces with complex holes, but I'm sure you can find DXF files for laser cutting other places (I found some once, but I have no laser cutter).

I'm sorry I couldn't help you.

I'm so glad you did this! I had tried another iris box design, but every little peg/part broke. I had thought about a modification like this, but I hadn't done it. I think this will be my next thing to print! 

I've printed it but can't figure out how to assemble it. Could you add some photos of half-assembled showing how to put screws?

I'm sorry! I forgot, on the top of the box, you should put 5 M3 Nuts (or equivalent), and some M3x20mm screws through the holes (you should watch the picture where the lead is of (you can see all the screws).

Then you need 5 small bolts (around 10mm) that have conic head, and put them through the holes that are free. You should push them (not screw them) till it pops out of the other side (look at the pic). In those screws you should place the big hole in the leaves. The grove in the leaves should be facing down and the other screws (the ones with the nuts)  should fit in that grove (for the grove is the guide to force the movement of the leaves).Then you just put the ring on top of everything making the conical head screws fit on the holes in the ring and screw them, but not to tight.

I figured it out!  Works great. Thanks a lot!

I'm glad you made it work!

Thanks for quick response. I'm just not sure how
these "conic head" screw look like. Do you have a picture of it?

I thought this was meant to be used as a hole for peeking through your front door. could be cool, but drafty!
