Cutting board insert shelf

Solving a unique problem: holding cutting boards in a cabinet when the space intersects with another piece. Also, A beginner's attempt to use Bambu Studio to solve a real-world problem. The drawer/cabinet holds cutting boards and other large awkward kitchen pieces. New cutting boards needed to be supported, but they also have to overlap with a large cutting board. The solution suspends the shelf (snugly) in the space with a cutout in the open end for the other cutting board. I was concerned about the stability of the free end of the bottom, so added a lip and support beam at that end - which also prevents the boards from sliding out. Added support beams on the full end as that end seemed too flexible in early test prints.
