What should I make with a Haas VF2?

I have full access to a Haas VF2(3-axis) and I am wanting to use it, but I am kind of at a loss for ideas on what to make. I have made a few trinket sort of things so far, but I want to make something cool and useful and even maybe things I can sell on eBay. I have interests in/access to dirt bikes, cars, trucks and other mechanical things to make parts for. I am an engineering student and I am familiar with CAD and I have learned CAM on Fusion 360. Any Ideas?
