Edit Reason: Go to the right place, links! *whip*

I have adjusted my eyebox model a bit to accommodate the flange, and printed again. The first time I was pretty close, but the flange indent had a gap because I didn't pay enough attention to the reference photos. Second time was pretty close to perfect, aside from some quality issues with my prints that I haven't yet sorted out following my hotend upgrade.

I added tabs for the mounting screws. They should clear the lens retainer just fine.
The above print worked well as-is, but I'll be tweaking the measurements slightly to make it fit better.

I will supply a proper PDF version of the plans once they are further along, but for now here are some screenshots from Fusion 360. They will get more complicated as I add details. As with all of these images, clicking will take you to the larger image.

You'll notice that I just take one edge of each "eyelid" (the top and bottom extensions of the eyebox in front, the ones that the lens holder sits between) and project that line straight back to meet the slope of the top and bottom walls. There's no particular reason I did it that way, and I could save a bit of plastic and weight if I just continued the walls further and joined up with the eyelids only a few mm behind the lens holder.
Edit: Nevermind, I've already done it, and updated the drawings. They also now include the distances of the rear face (on the overview sheet).
(I'm hopefully going to be doing animatronic internal eye mechanisms to go inside these (think something like a simplified version of Johnny 5's eyes from Short Circuit), assuming I can fit them and link the mechanisms together. I'm also wanting to fit a Raspberry Pi camera to use with OpenCV onto this mechanism, in order to allow Treadwell to automatically focus on faces when I'm not puppeteering the head myself. If you've seen the latter half of part 25 of James Bruton's Ultron build, you'll probably have some idea what I mean. If there's insufficient room with servos for the eyes as well, that camera will have to go outside the eyeboxes. Which is fine; then I would be able to have matching lenses that weren't just shells.)
