Prompt

Make a U-shaped channel bracket built from three rectangular plates fused into a single solid. Bottom plate: x in [0, 30], y in [0, 40], z in [0, 4]. Left wall standing on top of the bottom: x in [0, 4], y in [0, 40], z in [4, 30]. Right wall standing on top of the bottom: x in [26, 30], y in [0, 40], z in [4, 30]. Output a single solid.
