I was a bit bored so I made a repeating pattern.
A few attempts, a few changes and now I'm happy with it.
It's a 2D chain, printed without supports.
It's kind of like a fidget spinner, just for fun.

I usually print Petg and it went smoothly, PLA will be just fine.

0.4mm nozzle
layer height 0.2mm

Photographed on a potato, just print it and enjoy.
