A very useful part of a technic workshop: it joins directly an axle with a ball pin and allows to build complex segments useful in cars and linkages.
A made the delta frame joining different section of a common frame so it is not perfect but it made its job. I post this file after a comment so if you have any question feel free to write in the comments. Hope you find it useful.
