Iris Mechanism Generator (Variant 1)

This is another variant from my Iris Mechanism Series, which I originally started designing back during the pandemic—and now, after several years, it receives a much-needed update.

The original model I uploaded a few years ago was:
👉 Iris Generator Model-1

However, it was unfortunately marked as "tainted due to a violation of community guidelines" by GrabCAD.

This variant uses flexible overlapping blades, inspired in part by this post:

In this design:
- The number of blades is calculated automatically based on the thickness of the base plate.
- There are a few geometric constraints: the inner radius must be smaller than the outer radius, and the maximum supported configuration is when the outer radius is exactly twice the inner radius.

The blade shape provided is just a draft, so feel free to customize it to your needs. Use the sketch as a starting point, and modify it to suit your aesthetic or functional goals.

⚠ Note: Be sure to open the full assembly, as all blade dimensions and positions are driven by equations and references from the assembly itself.

Feel free to use or adapt this model however you like!
(And hopefully, GrabCAD won’t flag this one again 😅)
