Cage Ball

Simple design that pays homage to the US Air Force engineer who visited my Technology Education class in High School. He described this "thing" that they made that had a loose ball inside but had no seams. That was the first time I ever heard of 3-D printing. I never forgot that description and 25+ years later I was able to recreate the design.

Ball attaches at 2 points and simply needs freed once printing is done.
