Nice unfold! Thats it, 9 sides in the main lenses! At least , thats is my conclusion from studing photos!
SketchUp is/was free, and I'm used to it, but if it more useful on other file format, just name it, I will do my best. You can also try to converte it online, there are a number of free file converters available.
As for the lens model, I tought maybe a paper caje, with the transparent printed acetate glued on the inside?
