Spiraling Gear Chain - Fidget Toy (V1)

This is a new fidget/stim toy I'm calling a “Spira Chain.” You can expand it, flex it, wiggle it, roll, and unroll. There is an texture element from the gearing and mechanics that should give the sensation it is partially wrapping itself up into a spiral shape. This version has a 20mm width. I'm considering on the next version to make it smaller and remove some of the sharp edges.

Each chain link should take about 5.27g at 15% infill, costing about $0.11 and taking 22min.
It takes eight links to make a revolution, so each revolution is about 42.16g/$0.88/176min.

Pictures are of 25 chain links printed on Bambu X1C at 15% infill. I used a brim but I don't think it's necessary.
