Flexible Iris Fidget

A unique and clever iris mechanism fidget toy that's deeply satisfying to play with, and potentially enable unique applications in contraptions. Originally uploaded by Phyti1 on Thingiverse, based on a design by Flexsys. Printed at roughly 60% scale for a roughly half hour print. Supports enabled - requires a bit of time to separate the two concentric rings from each other - be careful not to injure yourself if trying to separate with a sharp object, a credit card should suffice.
