Animorphic Camera Lenses

My friend has a fancy camera, and wanted to try out an animorphic lens filter. Before he dropped the cash on the expensive ones (like this: https://www.bhphotovideo.com/c/product/1338799-REG/vid_atlantic_vamp77cbkh_77mm_cinemorph_filter_kit.html) we tested by printing some basic ones that he attaches with adhesive strips.

Since he had different size lenses, I made 3 sizes: 47mm, 67mm, and 77mm. All of them are 2mm thick to make quick prints that will fit to the camera lens easily.

If you need a custom size, I've included the STEP or F3D files for the 47mm one. I then just scaled the object non-uniformly on the X and Y axis to make other sizes, leaving the thickness at 2mm. Feel free to make your own if your lenses are different sizes.
