Prompt
Make an L-shaped mounting bracket. The base lies in the XY plane, occupying x in [0, 50], y in [0, 30], z in [0, 4] (50mm long, 30mm wide, 4mm thick). A vertical wall stands on the +X edge: x in [46, 50], y in [0, 30], z in [4, 30] (4mm thick, 30mm wide, rising to z = 30). Two through-holes of diameter 5mm pierce the base parallel to Z, centered at (10, 15) and (35, 15) on the top face. Output a single solid.
