So had parts printing yesterday but had to make some changes which I was able to print today.
I printed the frame and decided the overhanging bits on the bottom plate where the "flashlight" goes weren't needed and served no purpose so I removed them.
(Version 1)

I then printed the pivot plate out standing up on the print bed which caused warping, after trying it on the skull I found out it was binding up pretty bad which at the time I figured it was because it warp so I went modified the model to give some extra room where I thought it was getting stuck.
(Version 2)
I removed the overhangs I then also removed the indexing tab from the frame putting it instead on the pivot plate.
After getting the pivot plate printed out I found that fit better but was still dealing with what I still thought was warping even after I flared the bottom part of the tracks out, so I carved it out some to see if it made any difference but nope. I then carved the whole thing out and it was still binding up.
I then got the idea to put a few marks on the skull part of the track with permanent marker, forced it to turn a bunch, pulled it off and saw that it was binding on the bottom edge even though I had given both parts enough room.

so I had to go rework the pivot plate track model more.
(Version 3)
No changes to the frame were made other then opening the channels for the track to fit.
The only real change I had to make was to the pivot track, also printed it so it was laying on the print bed.
Tried it on the skull and it turned perfectly.
Some side by sides.
Top to bottom versions 1,2, and 3 of the slider for the "flashlight".
Now that it actually works as intended I can move on and get the other parts printed.

Going to get it glued together tomorrow after I print the outer shell and can try it.
I still have some parts to fix: the neck(to fit a known size pipe), the chin, the chin sensors, and the headband.
Well that's all I've got for now, more pictures soon.
