I have been playing with braid designs since making a braided wedding band and matching bracelets for my fiancée. I tried stretching out the weave of the braid, to the point that the strands become separate from each other. The result can't be printed in metal (at least in any of Shapeways' processes), but in return it becomes very flexible! This design is made of a braid of nine strands, separate but interlocked. I also have a wider, eleven-strand version. As you can see in the photos, these bracelets are very flexible. The weave changes shape, becoming thin and solid or wide and widely-spaced, depending on how the bracelet is flexed. They even bounce.
Please select a size when ordering. The lengths listed are the inside circumference of the bracelet in its relaxed state. They stretch a bit, which makes it easier to fit them over your hand. If you would like a size other than the ones listed, just choose 'other/custom' and tell me what size you would like in the 'special instructions' window. You do have to create an account with Shapeways to place an order, but it only takes a few seconds!
Note: I have only printed this design in the 'strong and flexible plastic' materials. It also meets the design rules for the detail plastics materials, but I don't know how strong the result would be. I think it would look pretty cool in the transparent detail material, but it might not be suitable to wear.
