just a Galaxy Spring Joint how to use: unpack pakage then drag and drop the prefab into the project and then make a rigidbody with all the constraints locked on the part where you want to control it from eather one of your hands or one of your fingers. then drag and drop the rigidbody (hand or finger) into the spring joint's connected body. After that its just a toggle depending if you are using 3.0 or 2.0 thats up to you
