I have a file of a 3d design for a prop from a tv show called Johnny Sokko & his giant robot. It is of the wristwatch controller. My problem is creating a small enough hinge for the two pieces to be connected as well as opening and closing correctly. Is there anyone who can help without charging a lot? I am on disability from open heart surgery back in 2022. I need help with this, and I will pay if I can afford it. Please someone help me I really need your help-I do have stl files which I created through tinker cad.
