The first thing I ever made in Fusion360. A simple stand to hold 5mm cardboard, to create a stand to house your sheets and to be able to store things underneath, like your ships and hand of cards. My players loved it; it was their favorite upgrade to my setup.

The 5mm cardboard is literally just the box my 3d printer came in that I cut to size. So I'm assuming this will generally fit most cardboard box material.
