How to Simulate Camera Aperture Diagram?

Grasshopper
1

Hi everyone,

I’m working on a simulation of a camera aperture diagram in grasshopper. I got the Blade to rotate properly on one end along the green line (right pin). But the other is not working (left pin).

The left pin should move along the yellow line and in the linear slot behind it. Right now, it is moving in a weird loop (black).

Could someone please help me to add this constraint?

Attached are my rhino and grasshopper files.

Thank you so much!

You’re welcome.
As you might have noticed the first rotation is no longer needed.
