I made this as a proof of concept. It worked, but if I want the claw not to flex, I would have to make the claw out of thicker paper, or glue two pieces together. To make the claw open you would have to pull the string. As ar as I looked up online, no one created this type of claw designI havent made a template for it, but if someones asks, then I will when I have some time, same for isntructions
