2 ball joint adapter parametric

I made a parametric model in order to attach an off the shelve wireless charger to a very rugged RAM Mount style holder. Parameters influence: Parameter NameDefault ValuesWhat changesbig_ball38 mmThe size of one of the balls. By default it is the larger of the twosmall_ball17.1 mmThe diameter of the small of the 2 ballsthickness_big15 mmA diameter of the arm connecting the 2 balls that comes out of the "big ball”thickness_small8.7 mmA diameter of the arm connecting the 2 balls that comes out of the "small ball”length_neck15 mmThe length of the arm that connects the 2 balls Prints with supports rather ok.
