I'm still pondering the Creative Commons license issue. I'm not certain I want to give up the ability to sell the eyes as add-ons to other figures (and prevent others from doing so).

Fair enough! I'm quite happy to have the eyes as add-on props with a separate licence.

Edit: Bear in mind that the CC licence would only cover the eye geometry, and only the particular mesh version that we'd include into the Antonia figure. We wouldn't make the material settings part of the base figure and could thus easily put them under a separate licence (we could probably licence different parts of the base geometry differently as well, but that doesn't seem very practical). So the main parts of your IP would still be protected.
