how to simulate origami properly? I have super struggled with this model and rigging for a month without weekend. I made this rigging object combining copy rotation + transformation. Because I thought some hinges should go faster than others to keep them stick together.



But as you can see in this file above,it does not work. The centre fall apart during the animation. How I can make them get together during the animation?
Look at it in Front View (Ortho). Note that with the rig you have it is designed so it will fold into a square, ignoring the end pieces. If you want something else like a pentagon maybe you should start with that shape and work backwards unfolding it. Or just change the shapes of the end pieces to be more like the rest.
