This is a simple chain, the links can be connected using short lengths of filament - it simply loops round so if you want to use it as a bracelet or watch chain, you'll need to make it large enough to slip on and off.

If you'd like to learn more or make your own, I wrote an instructable detailing the design process and also the assembly process which you can see here: https://www.instructables.com/How-to-Make-a-3D-Printable-Bracelet-Using-Tinkerca/
