Ball Cap Rack

I have collected about 40 ball caps over the years and they were all stacked up in different rooms in my house. Some were nostalgic and I wanted to preserve them. I have included two rack designs, one with a hook and one without. This is a case of function driving form, so they are not very pretty, but they work great. They are non-symmetric so they can be printed without supports. The inside of the cap and the bill are well supported to preserve the shape. .stl's, .step and Fusion 360 desig
