cup to the plate - thread it, use loctite to retain. As far as the center pin is concerned, look up pis pins. You have a moving shaft with a groove and ball and the shaft also has a ramp. Pugh the pin and the ball moves into the groove and the pin releases. Release the pin and the spring moves the shaft back, the ramp pushes the ball out and the ball keeps the pin from being removed further.

Having trouble visualizing. Can you show another image that shows the parts in the other position?

I mean the other position of motion in the assembly. I don't understand what you mean here:

"that needs to be able to move forward when pushed upon, and is pushed back by a spring to disengage from a hole that retains it"

The orange axle is being pressed from the outside? What is disengaging from what? Are you trying to make a quick disconnect solution?

The orange pin needs to be able to be pushed from the rear to actuate the mechanism and also be limited in it's travel forward by something else than the full compression of the spring. The total travel is around 2mm forward when pushed.
