I printed this at 80% scale. PLA 0.2mm layer height.
It should be printed with no supports and no raft.

I have not put the work into it to actually make this a customizer.

You can print multiple units and the small insert can be used to chain multiple prints together.

It was designed with 2 rotating joints so that it could bend in every direction.

Although I designed it as a necklace, it ended up more as a fidget device. It is very satisfying to move it around in the hand.

Try printing it at various scales. I am not sure how small you can make it.
