CAUTION: Order TWO of these for a complete set. Some postprocessing needed.
Ring Bracelet is based on an
idea by Carl Hoff. Carl's idea was to have a puzzle ring, in which the set of rings is linked in a loop, similar to
Weave Five, such that the scrambled puzzle can be worn as a bracelet. He calculated that 10 rings would be needed for this. Bram Cohen analysed what the order of the rings should be in the solved state. Oskar found a weave that worked, and he produced
a few prototypes in plastic to perfect the design.
This is a prototype in metal, which works perfectly. A limitation of the Shapeways interlocking metal process is that it only supports up to six interlocking parts, not ten. This was solved by splitting the bracelet in two identical halves, order two, cut some rings, link them into the bracelet and solder the rings. The solder does not look so nice, but the result works fine.
