I am not sure what you mean.

I am interested to see what the out come of this is.
I am actually using Blender 2.45, it is free and pretty easy to learn, especially for stuff like this. I have never considered lexan, but I will look into it.
These are instructions as to how to build your own iris. Read before starting.
1. Cut out three rings, A, B, and C.
2. Divide one of the rings into thirds and shape them into points at one end.
3. Grab Six nails
4. Punch a hole in both corners of the petal.
5. You should have three petals that look like picture A
6. Take ring B and punch 3 holes near the inner edge that are 120 degrees apart. (Refer to Picture B)
7. Here is the tricky part.
7a. put all of the petals in ring B like in picture C1
7b. for each outer nail. mark the spot on ring C that correlates to that nail if the petal was matching the contour of Ring B.
7c. Now turn the petals inward as much as you wish. then do the same marking for the outer nails, you should now have two points a starting point and an ending point for each nail.
7d. Draw a line between the two point and make a slit, then cut out the sides of the slit so that there is enough room for the nail to move without too much friction. (Refer to picture C2)
8. Place ring C on top the petals so they are sandwiched between C and B.
Turn either ring.
Alternatively you could use the cutouts I supplied.
