Iris Mechanism Generator (Variant 5)

This model is part of a series of Iris Mechanisms I began designing during the pandemic, and it now receives an update after several years.

The original model uploaded a few years ago is available here:

Unfortunately, due to GrabCAD’s community guidelines, it has been flagged as “tainted due to a violation of community guidelines” and is no longer publicly visible unless accessed via direct link.

🛠️ About this Variant
In this version, the actuation is achieved by rotating the driving plate. This plate interacts with slots (guides) on each leaf, which in turn execute the opening or closing of the iris.

The mechanism has been successfully tested with 4 to 7 leaves, though I do not recommend using only 4, as the slot approaches too close to the edge of the plate. Suggested maximum opening angles (r_max) are:

4 leaves → up to 45°
5–6 leaves → around 40° to 35°
7 leaves → up to 30°

Please review the model carefully and test parameters cautiously before applying them in a final design.

Feel free to use or modify this model as you see fit.
(And fingers crossed GrabCAD doesn’t report it again 😅)
