This print in place design embeds spherical rotating beads in a customizable cuff bracelet. The model comes from Tinkercad Code Blocks
https://www.tinkercad.com/codeblocks/fjyDH4QxsuJ
and the size can be easily modified by changing the first three parameters defined in the code. (See image of Code Blocks below to view the parameters). The parameters define both the size of the hole in the center of the bracelet and the gap through which you slide your wrist. I've included two model sizes for download here, but it is straightforward to generate your own using Tinkercad. You may have to ask the Prusa slicer to fix some errors generated by the Tinkercad code, but it shouldn't cause problems with the print.
Once printed, simply twist the beads around a vertical axis with your fingers to break the support structure and allow them to rotate freely. It shouldn't take much pressure to do this.
