Prompt

Make a U-channel bracket as a single solid. The base is a rectangular plate 100mm × 30mm × 8mm with its bottom face on the XY plane, centered in X and Y (so it spans x in [-50, 50], y in [-15, 15], z in [0, 8]). From the left end of the base, a vertical leg rises: 8mm × 30mm × 35mm, at x in [-50, -42], y in [-15, 15], z in [8, 43]. A matching vertical leg rises from the right end: 8mm × 30mm × 35mm, at x in [42, 50], y in [-15, 15], z in [8, 43]. Drill two through-holes of diameter 6mm, axes parallel to Z, through the base only (z = 0 to z = 8), centered at (-25, 0) and (25, 0). Output a single solid.
