Prompt
Start with a rectangular block 50mm long (X) × 30mm wide (Y) × 20mm tall (Z), centered in X and Y with the bottom face on the XY plane (so it spans x in [-25, 25], y in [-15, 15], z in [0, 20]). Cut away the upper +X corner: remove material in the region x in [0, 25], y in [-15, 15], z in [10, 20]. The result has an L-shape when viewed from +Y. Output a single solid.
