Overly-complicated Flower-box Jewelry Box

About: Average everyday nerd who likes to be creative. Wrote and published a few books so far, but I keep my day job because I don't like being board.

A few years ago I had this idea that my wife might appreciate a jewelry box as interesting and as complicated as some of the bits of jewelry she kept in it.  every iteration got more complex and had more moving parts.  the final version, that I decided to build, has about 1700 pieces, most of them moving.  I designed it to be produced on a 3d-printer, and as you know, those are slow and take a lot of time to work.  It's not nearly finished printing the parts, and assembly is slow, but here is a rendering of the finished project.  If anyone wants to build it themselves, they can be my guest.  The assembly is pretty straight forward.
the CAD files are in AutoCAD 2012 Student edition, but that only matters if you are printing images from the file.  Remember, there's over 1700 parts, and I'm not done printing them myself.
I've uploaded the STLs here, and their print-quantities are in their filenames:
which means, there are quantity four of part03 in the STL, and you need to 3D-print the file 3 times to get the number you need for the assembly.
Also keep in mind that the fully assembled drawing file (with all 1700+ parts assembled) is just under 52MB in size, so downloads could take you a while depending on your connection type.  It's available at this location:


If I remember right, there's also a smaller drawer array inside the petal flower.  that's where all the jewelry goes.

    Or try SLA printing for the parts. Smoother, and maybe increase the thickness of the parts that tend to flex. Wonder if CNCing the materials would be better or make a mold of parts to injection mold them.

    when designing this object, i was brand new to engineering and 3D printing. sure the mechanism could work, but the deflection and material properties under stress allowed too much play and slip in the parts to be too elegant. I eventually had to scrap the project and recycle the ABS back into filament before it was more than half done. the first level petals opened good, but the compounded flexing and tolerance issues became more than the production method could handle. Pretty in render, but not realistically possible with this method. I have been intending to take the project down from here, but I was hoping somebody else with real engineering experience, and the required time on hand, would redesign it to work properly.

    So the mechanics are good, just need to use strong enough material and maybe increase the thickness of the links and petals? Perhaps with PLA instead of ABS

    wow i love the box wish i had a 3d printer guess i have to save up
