This ball joint was inspired by others' projects, of course.The notable things here:sized to fit 1/2 inch pvc4 control holes in each piecenew for mk4, wedges to prevent twistingBy attaching a line to each control point, and running through the corresponding hole, the joint can be fully controlled from elsewhere. For my test piece, I used fishing line and a small #10 washer.
