With the success of my Linked Heart Necklaces, my boyfriend and I began pondering other lovey-dovey jewelry ideas. We both love the idea of a necklace where the halves fit together, but any two halves will fit together. The necklace must be as unique as the two people who share their love. Thus enters the Combination Heart Necklace, stage right!
Each necklace is randomly generated by a Blender script based on a random or entered number (in this case, 42!). There are over a half million possible necklaces, so unless this sells way better than I was expecting, it's guaranteed to be completely unique. Only your sweetie's necklace will match up perfectly with it. In addition, each half can be customized with your initials!
Just like a good relationship, this necklace was a joint effort. My wonderful boyfriend cyborg_ar is the one with the amazing programming skills, and this is his creation. I just have his permission to show it to y'all (and eventually sell it).

<3 that script is pretty comprehensive, all the customizations are fully automated to the point that it just churns out a STL file (had to write my own exporter as blender 2.56's was too buggy to be usable) ready to upload to Shapeways once it's done. That will allow us have very short turnaround times for our buyers!

Now that is extremely interesting. I hope you'll pardon me if my first thought is "how does it work?" It's cool if you don't want to explain all the details, but here are two burning questions I have:
How did you induce Blender to generate letters via python?
I'm also curious how you ensure that a random combination would be printable? I'm assuming that the combination is based solely on rotation of the ring-halves, and not on splitting up the ring halves into smaller segments (since I can envision that making some very unprintable combinations).

I made 26 meshes (one for each letter) named them letterX where the X is the letter and then made the python script assign the mesh data of the mesh objects in the initials. (the obj exporter doesn't automatically convert curves to meshes so i had to make that kludge, ideally i'd just have used text objects)

Oh i implement some vodoo magic and limitations to the movement of the rings to ensure all combinations are safe, (plus my script automatically places reinforcements to the mesh for optimal strength) still, i'm guessing at least a few thousands of those half million combinations are either a bit dangerous or too dull anyway, so we do a quick manual review before uploading, all takes minutes 
Right now we're organizing a bit to do some test prints and put this co-creator online also, would anyone be interested in a round medallion without the heart around it? (for a BFF medallion or so, or you just don't wanna be too cheesy) Where would be a good place for the initials?

A round medallion, minus the heart, would be interesting. I would strongly suggest creating a circular pattern around the combination section. I bet you could do something very similar to what the heart-shaped one has. Part of what makes the piece appealing to me is the intersection of curves.

The rings would go well in a lot of shapes, not just hearts and gears... More to think about!

 I recommend orders to be made in the details materials, those have better chances of meshing correctly.

So, these are not thick enough for a metal material?

With the recent confusion around metal wall thickness and what will print successfully, I don't want to offer it for sale in metal until I can order a metal print for myself.
