Elli here's the fruit of my efforts....
It might be that the things most useful to your graphist are these two jpgs showing the "floaters" in red. The images on the left are the meshes that were in the stl files that you attached; the images on the right are of curves that I created from the meshes. These images are in the attached zipped folders, along with conversions to ai and dwg. Each ai file has the meshes and the curves as shown in the jpgs. Each dwg file has the curves, scaled up to 35" (889 mm) in height.
I don't use Illustrator or Draw either, so hopefully this helps. I included the dwg files as that's a format that I'm more familiar with for this use.
I hope this helps!
