So someone mentioned this in a facebook group for retropie and I couldn't resist doing it. Immediately my first throught was to see if I could grab a green hamster ball for the sphere part and 3D print the rest. I was able to find the ball on ebay for not much cash when I get it in the mail I'll begin modeling the box and the inside logo bit.

Here is the ball I bought
