Salad container wall rack

If I can get this to work, it will mount on the wall and provide a handy place where I can hang a couple of the Rubbermaid containers in which I package the salads I take to work. This is probably too big to print on my printer -- it would take most of the bed, and at that size, curling is going to be a serious problem, so I doubt I will be able to make this work.
