My kid is really into Pokemon lately and wanted to have a Z-Ring bracelet. I tried my hand at making one based on artwork/gameplay footage/show footage found online, sized to fit my kid's wrist.

There is a hinge on one side and a latch on the other side. The model is print-in-place, but please exercise caution when moving the hinge the first few times as the tolerance is quite tight.

Plate 1 is the Z-Ring bracelet with a piece that needs to be glued onto the bracelet. Use your choice of glue. This should fit around a 54mm wide and 42mm thick wrist.

Plate 2 has 7 unmarked Z-Crystals. Feel free to print them in whatever color you want. They should fit pretty tight into the gaps on the bracelet, but I would recommend gluing them in.

Plate 3 has a slightly larger Z-Ring bracelet. This should fit around a 65mm wide and 50mm thick wrist.
