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.
Now you know how AV guys have felt for the last few decades seeing BNC connectors on every piece of sci fi equipment
Is that a stepper motor coupling or am I missing something obvious?
Edit: I did not notice OP‘s comment sorry
It’s a flexible coupling for a drive shaft. It probably does show up on stepper motors for 3d printers. It’s used to allow for some misalignment between the motor and the rest of the drive assembly so there isn’t any damage to the motor bearings or binding of the shaft.
Is nobody going to talk about the PINDA probe on the left side?
