American Football Slingshot Toy

I designed this football themed slingshot in fusion 360 because I wanted a fun toy that can be used inside and outside. So I thought of a cool idea where I could make the goal post the main slingshot body and the balls could be footballs but I wanted to make it comfortable to fit in your hand so I had to make sure that the measurement were perfect. Do not scale anything down or up as it could mess up the way it fits in your hand and will mess up the ball.I have included a slo mo video so you can
