Link to full version of image that shows more mechanical detail. My previous laser cut prototype confirmed the need for this type of assembly jig.

Planning ahead for these types of assembly concerns is one reason CAD prototyping is so handy. Once the pieces are chemically welded together it will be slid off the top. The orange piece in the image below mates with all the vertical risers to keep them at right angles during assembly. Unfortunately this does not resolve the issue of the back of the eyeballs being visible when the eyes rotate inward, which is why this eye mech design is so atypical. The 5 degree reduction causes the eyes to face slightly more forward, which looks a bit better. The eyes are now canted at 40 degrees from the center of the head. I have fine tuned the eye mech into something that works within the unique constraints of this character. Much progress has been made on my CAD work for this project in the last week.
