H-Frame Clamp Rack

I’ve been working on getting my shop better organized and one of my top projects was a clamp rack. Before this I had clamps on shelves, clamps in drawers, etc. The wood in this project is 100% scrap. The base is made from plywood cabinet doors and the upper H-frame is fir (I think) from some old shelves. I bought the casters, but that was it for purchased parts. I would have liked to make the base a bit wider for stability, but this is what my scrap pile gave me. It’s all screwed together (no glue) so I can change the design in the future if needed. I looked at other racks before I came up with this design and I saw a lot of racks tailored to the clamps with notches of just the right size and spacing etc. But then I thought, clamps are good at holding things, so they can hold themselves to a rack. So I went with simple cross pieces and a couple “arms” at the top that can accept just about any sort of clamp.
