Prompt

Make a double-D profile shaft as a single solid. Start with a cylinder of diameter 40mm (radius 20mm) and height 60mm, with its base on the XY plane (z = 0 to z = 60), centered on the Z axis. Mill a flat on each side by subtracting a rectangular block from the left and from the right. The left flat is at x = -14: subtract all material at x < -14 (i.e. remove the cylindrical segment from x = -20 to x = -14, running the full height z = 0 to z = 60 and the full cylinder width in Y). The right flat is at x = +14: subtract all material at x > 14. The result is a shaft with flat-to-flat width 28mm and circular arc sections of radius 20mm on the front and back (+Y and -Y sides). Output a single solid.
