Looks like the prop makers of the movie used a lead screw coupling and bashed it together with some tubes and other parts. When I saw it I went like the Leonardo DiCaprio meme pointing at the TV.
There used to be a subreddit called /r/thatsabooklight that would point out this kind of stuff in movies and tv shows. Was a fun one to follow.
Is that a stepper motor coupling or am I missing something obvious?
Edit: I did not notice OP‘s comment sorry
Is nobody going to talk about the PINDA probe on the left side?
Now you know how AV guys have felt for the last few decades seeing BNC connectors on every piece of sci fi equipment
I see a two post height gauge as well.
