Tennis Ball Pressurizer

grabcad

My redesign project will be based around tennis. Due to the fact that I am a tennis player one of the things that I am constantly having to do is test the pressure in tennis balls to see if they are still playable. With this redesigned tennis ball pressurizer, you will be able to accurately check whether or not the ball is in adequate hitting condition. The basic structure of the tennis ball pressurizer will consist of; the 3d printed base (3 vertical support beams, top and bottom cupped bases, connecting crossbeam, arm), a small scale, a mechanical powered motor (connected to the arm), a mechanical arm will be controlled by a switch (when flipped the arm will be pushed downward). with this action the ball will be pressurized at a constant pressure and you will be able to accurately see the pressure of the tennis ball on the scale.
