A flexible, tactile, customisable bracelet which makes a pleasant jingly, rattly noise.
The bracelet is made from a number of interlocking segments made from concentric cylinders. One openable segment can be included to allow the bracelet to be fastened when on the wrist so you don't need to oversize it to go over your hand.
Superseeded by this: http://www.thingiverse.com/thing:57780 which is more comfortable to wear.
Open in customiser and play.
The main customisable features are the diameter of the wrist and the height and diameter of the cylinders forming the segments. However there are many other parameters that can be tweaked including wall width, gap between segments (useful if on the first try the inner and outer cylinders stick together), number of struts and whether or not to include an opening segment.
It should print well, but I had some trouble slicing with Cura - worked fine with Kisslicer.
