Iris Mechanism Generator (Variant 6)

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 policies, it has been flagged as “tainted due to a violation of community guidelines” and is no longer publicly visible unless accessed directly.

🛠️ About this Variant
This version features somewhat triangular leaves that slide against each other. The mechanism operates through two plates:

A base plate with straight linear guides, which define the opening/closing position of each leaf

A driving plate with curved slots, which actuate the iris motion through controlled displacement

This model is a schematic representation, so any manufacturing considerations—such as tolerances between pins and slots—are left to the discretion of the designer using this as a starting point.

⚙️ Notes
Be sure to open the assembly file, as the parts are dimensionally linked to the assembly (parametric relationships are defined there).

Feel free to use or modify this model however you'd like.
(Let’s hope GrabCAD doesn’t flag this one again 😅)
