Because of a little trouble, it came almost a month after I ordered it, but it arrived and it worked first shot. Ok I cheated a little bit, I had it set up 2 different ways to see if one, the other, or both ways would or wouldn't work. Well one way fused but the other, worked perfectly. With a snug push into place, the ball is locked into the socket. After playing with it all weekend it now moves very smoothly in the socket. I showed it around and almost everyone said so?. SO? its a damn 3D printed stainless steel freely moving joint! Anyways hope you all will appreciate it more.index.php?t=getfile&id=3239&private=0

Sweet awesomeness. You got any dimensions/tolerances/drawings for it? Dimensionally, what worked and what failed? Looks like the socket is only half a sphere, but has two little arms that extend past that point to hold the ball in place, while reducing insertion force?

Ok, here's the item that I ordered.

http://www.shapeways.com/model/92071/joint_test.html

It was a total of 7 pieces. The tiny ones didn't come out, I figured as much, so I was planning on having to use something else, The idea was those larger small parts would slide into the end joint, and the two tiny pieces would hold them in place, well all the holes fused Sad oh well because the other section worked perfectly. was able to with some force get it to snap in and still hold firmly in place. I'll get you some dimensions in a bit. a little busy atm.

Ok, got some time to give you some dimensions. The Ball is .2" in diameter. The socket is .22". The clasps are .04" off center so at the tightest point the diameter is .197". The tips are rounded so that it's a little easier to snap in place, and seeing its .003" tighter then the diameter of the ball, it holds in place.

Well I made it so you can order the working piece, piece by piece. A bracelet worth would cost you $62.10 (estimated based on 18 pieces would give you about 9 inches in length, the length of a standard large male bracelet) http://www.shapeways.com/model/110460/single_joint.html

Cool! Just what i've been looking for. Does it work in any other material, though?

I designed this specifically for stainless, and only ordered in stainless, but this same sort of design should work for other materials, and be able to be more secure, as the knobs holding the ball in could be larger as they'd be more flexible to allow the ball into the socket. I had to make it so there was just under clearance so that with force it'd pop into place, and I'm sure with enough force you'd be able to pull it apart again, as stainless doesn't like to budge as much as say plastic would. I would not try it with sandstone or glass.
