I'm trying to replicate a prototype floor jack that works exactly as the one posted in the picture. I am using a jigsaw and some MDF to start. I plan on using a stepper motor to turn the threaded rod in order to raise/lower.
I'm just wondering if anyone had some suggestions on how to construct the joint in the top right. The threaded rod needs a little bit of play so that the angle doesn't snap the plastic. I know this isn't quite Arduino, but I plan on using Arduino to control it Any help/feedback is greatly appreciated.

Why don't You take a cloose look at an existing jack and copy that?
Interesting. Where is the stepper motor mounting? Why do you need the stepper motor to control? Is it for precise movements or just to lift the hinged arm?
I would think the right side joint would need to have something like an eye hook that was fixed to the threaded rod. A bolt or pin would go through the the “eye” and as the stepper turned the threaded rod this would either raise or lower the hinged arm. What are you planning to use it for?
I would cut a piece of square brass stock with the length matching the width of the plastic pieces. Then thread the middle of the piece to match the threaded rod. Finally turn the two ends of the square stock to an appropriate diameter to match the pivot hole in the end of the plastic. Then assemble the device.
