I was doing some brainstorming for gifts that I could make for my wife and daughter when I came across an interesting color changing filament. The color combination reminded me a lot of the brass and jade jewelry that I often saw in the markets of Beijing. When I went for a search for some of the ancient Chinese coins I could not find any in Thingiverse so I fired up Tinkercad and created some of my own. The first coin is in traditional Chinese characters and represents money, the second one in simplified and represents peace, and the last is a blank one if you want to remix a customized one. My pictures have them tied up with simple twine, but I found some red cord to make some proper bracelets and jewelry.
Here is a link to the filament, the colors easily change with body heat:

Some red cord that I found to knot the jewelry together:
