mechanical iris V2 | print in place | fidget

It's me again!

• For the people, who wanted handles: Check out Version 3 with added handles for much easier and smoother operation here: https://makerworld.com/en/models/775278#profileId-711757

After receiving feedback from some people on the first version of this mechanical iris that the tolerances were too tight, I have now created an adjusted version of the model. This way, even those with less-than-perfectly calibrated flow rates have a better chance of achieving a successful 3D print.
