I figure it could have looked more realistic if I used other filament, but I can't complain about the model.

The mechanism behind it was really a cool idea, but I think it is not too comfortable to fidget with at the size the base model comes in.

High quality model, but it has the problem all fidgets that utilize bearings have in common: it needs time and usage to get fluently working. Removing the supports was also a bit annoying because of the narrow gap in the middle, which made it hard to remove. Else very good, would print again👍!
