The sculpt itself is separated from the joint system. This means you can adjust the tolerances of the joints by printing them separately and modifying the exposure settings either in the slicer or the printer.
Another way to control tolerances is through the shape of the balls themselves. They have a slit which allows you to place a piece of rubber for example in order to increase the grip of the socket. I demonstrate this in the assembly video.
