California Iris flower

I created a model of the California Iris flower, in openscad. Notice the petals are slightly different. Each petal is composed of 4 bezier curves!
The print shown here has been printed with petal thickness of 0.5mm, which most printers won't attempt.
My .stl is therefore 1mm thick petals.

Apr 30, 2021, I added CA-Iris-100-outer-2mm and CA-Iris-100-inner.stl, that is 2mm thick petals and separated the outer from inner petals. They must be combined with a drop of glue! Hopefully these separate petal sets are more easily printed!
