Prompt
Make a flat T-shaped bracket lying in the XY plane, 5mm thick (z = 0 to z = 5). Horizontal bar: x in [-30, 30], y in [0, 20]. Vertical stem extending in +Y from the middle of the horizontal bar: x in [-10, 10], y in [20, 50]. Drill three through-holes of diameter 5mm, axes parallel to Z: one at (0, 45) at the top of the stem, and two on the horizontal bar at (-25, 10) and (25, 10). Output a single solid.
