The eyes are 4mm thick with a 90mm base (white), 58mm iris (black), and 14mm reflection (white) that's a negative part cut from the iris.
Depending on your version, there may be small plastic notches at the bottom of the eye housing. I had to file these down for the printed eyes to adhere properly.
This is my first upload, so please let me know if it works, helps, and needs to be deleted.
