Summary

This is a completely rebuilt version of my original iris door box. The walls, leaves and top ring are much thinner on this version, reducing material and print time. The mechanism is also easier to assemble and adjust.
They are designed to work with a specific screw diameter so sizing them up or down may not work.

Instructions

The box assembles with screws and glue. Written instructions are included in the TXT file.
My settings using ABS on a MakerBot 2X have been:
Gear ring and slot ring - .2 layer/ 10% fill/ 2 shells
Leaves - .2 layer/ 10% fill/ 1 shell - This is important, as I have found that more than 1 shell can make sloppy leaves that don't fit well.
Base - .2 layer/ 0% fill/ 2 shells - the 0 fill is important here since the walls are so thin. I find that using anything other than 0 shakes the machine like crazy and tends to jam the nozzle.

I'd really like to make one of these, but don't have access to a 3d printer...would you please consider enabling this project for printing? I think I saw 3d Hubs has added an app for it.

Thanks!

I'm sorry wtf is the " Iris_SM_leaf_jig.stl " that i printed ?

Read the instructions. It's a jig to aid in assembling the blades. Only really needed when assembling a bunch.

Glued the top to the base and sealed it shut... :/

What was the screw size that you used?

I don't find screw that fi with the original size, so i fucked up one model and lot of plastic

Awesome! Your model has been chosen as one of the Top 3D Printed Christmas / Holiday Models this year. Search "Top Free 3D Printed Christmas Gift 2015 Printing Ninja" to see. (sorry thingiverse bans url addresses)

Made countless boxes now maybe 15, I open up the leaf hole to 3mm (with a drill bit) which gives clearance for the screw resulting in a very smooth opening and closing action, great design my friends love them. Regards John UK

Hi, as i have just print one and after i fix all together the opening can't be open, can you please advise? sorry for the trouble and appreciate your kind help.

Thank you for sharing your design. My little girl love that small box.

This is a cool concept

Brilliant, thanks for the redesign printing now - regards John

Perfect A+ my kid love his new box :-)

Love the look of this. Though if the chevrons on the top plate don't serve any purpose I think I'd round it off and install 9 of them at equal intervals on the top. Make it into a Stargate.

Soon to be leaving thingiverse because of Makerbot's behavior towards open source.

How do you open stuff in customizer?

This isn't built for customizer.

I'm curious as well about a medium or large version? Or what scale to change it too and the screw size that would work accordingly?

Anyone else having trouble fitting the ring onto the base? The base fixtures came out well, but the holes in the ring are not wide enough to fit onto them. I printed a few rings with different settings but so far I can't get any to fit.

I had to drill the screw holes.

Does anyone know what will be the metric equivalent of the required screws?

M3 x 5 or 6 should work ok. Will add that to the instructions.

I used M3 x 6 and they were OK, I had to drill the holes though... That may be a printer thing though

Thank you. I will try to make it tomorrow.

This is really nifty! I built one and it works pretty well, despite me not using exactly the right screws. What software did you use to model this?

Cinema 4D which is a poly modeler. CAD would have been better but my background is in animation so I used what I know.

This IRIS box is really cool and your decision to use metal fasteners is a good idea. After printing my first box from the Thing Files I have discovered a possible problem with fit. The printed pins on the ring have a larger diameter (3.5mm) than the leaf's slot width (<3.0mm) and therefore cannot be inserted into the curve slot. Possibly the dimensions got switched? That is the slot width on the leaves should be 3.5mm and the ring pin diameter should be 3.0mm? Or better yet, the leaf slot could be 4.0mm! Please advise. Kind Regards

Hi glad you like the iris box. I suspect that your problems maybe resulting from tolerances on your printer. These are the same files that I have printed 100+ boxes from and have been downloaded 7k+ times without any issues. I would suggest trying a smaller number of shells and see if that does the trick.

I was able to calibrate my machine and the iris box print worked very well. It made a big difference. Thanks for responding.

Will you release the medium and large versions too? I'd really like a slightly larger box

if you use a program like cura to slice, you can scale the STL to whatever size you want.

I'm confused now because the description says scaling will not work due to the screws and holes?

While you can technically scale the whole thing in whatever slicing program, it's a 'precision' mechanism which I designed to work specifically with #4 screws. If you scale it up, the exact right size screw that fits the bigger version has to be found or the mechanism won't work properly. When I designed the large version I couldn't simply scale everything up since it would require gigantic screws that wouldn't work well and the leaves get super fat, etc. So I had to completely redesign the mechanism. This would be far easier to do with a CAD program but I used a polygon modeler. I have not uploaded the medium or large versions yet.

Coo! This one actually is printable! I like the slim design too.

Now someone please make a spring powered iris box where you push a button and it opens automatically :D

I think this box should be V4 not V3 since we already have a V3 iris box and this one is a improvement.

Love it.

One little change I would make however is to ever so slightly thicken the ring and leafs so that they are not quite as delicate as they currently are. Thickening would also allow for a bit more substantial plastic pivot's on the ring portion. This is a very minor point however.

I do agree with the design theory of this box, in that it makes use of small screws for the pivots. This results in a much more durable and usable container. Previously 100% printed Iris boxes were to breakable to use or open more than a few times. Or they wore quickly out and then broke. Or they were very difficult to assemble...LOL or all of the above.

Great upload thanks, look forwards to the larger and medium sized ones.

Thanks flateric,

This is v3 of a specific model, the Iris Door Box. I made the original, gwc made version 2 that used bolts in place of the pivot pins and this is now version 3 of this particular model.

I've printed dozens of these and haven't run into any problem with the slot ring or leaves being too flimsy. However I have found that slicing with certain settings can make the pivot pins really fragile and they break easily. Using 2 shells helps a lot with this as well as a level bed etc. I have some thoughts for making the pins a little tougher but that's down the road.

Nice, but why not make it fully printable like some of the other Iris boxes on Thingiverse?

I know, I know. ;) Mainly because I have yet to have one work very well. It tends to make the finished box bulky and the pins always break off and/or are hard to assemble. I designed the mechanism for something else originally and it needed to be pretty sturdy so I stuck with the design. I also like combining printed parts with real hardware and assembly rather than everything always being made of plastic. Thanks for the feedback MacGyver!

I was thinking about a slight modification to this design to incorporate more hardware and make it even more durable. Something along the lines of this make, where you can see the bottoms of the screws coming up through the gear:

But to make it even more durable, I might add some recessed nuts, like

Iris Door Box v3

Yeah, I like the "idea" of all 3d printed, but see no reason why hardware shouldn't be used. I've had to use hardware on all the iris variants I've tried. I actually forgot about that 8-leaf box. I'll have to give that one a go.

Also, Count, are you the one who did that Octo-sub? That thing is awesome. Just sayin.

Yep, the octopod is mine, thanks for the compliments. The iris box actually originated from the octopod since I had built the mechanism for the moon pool where the divers would enter and exit the vehicle.

I agree, I've printed nearly every iris box on here and the only one I didn't have to replace the plastic pins with screws was this one http://www.thingiverse.com/thing:23414http://www.thingiverse.com/thi...
