The prompt
REBUILD THE PREVIOUS MODEL FROM SCRATCH. Create ONE single continuous triangular rotor as ONE solid body. Top view requirements: - Start with one equilateral triangle. - The triangle must be a single connected solid, not three separate lobes. - Center the triangle on the origin. - Three equal sides. - Three rounded vertices with 15 mm radius fillets. - Distance from the center to each original vertex: 100 mm. - Rotor thickness: 40 mm. - Add one central circular shaft hole, 25 mm diameter. - DO NOT split the triangle into three pieces. - DO NOT create gaps between the three corners. - DO NOT create three separate blocks. VANE SLOTS: - Create exactly three radial rectangular slots in the same rotor. - One slot should point toward each rounded vertex. - Each slot is centered on a line from the rotor center toward a vertex. - Slot width: 15 mm. - Slot depth: 45 mm. - Slots must be CUT INTO the rotor but must NOT separate the rotor into pieces. - The three slots must be rotationally symmetric at 120-degree intervals. The final result should look like ONE rounded triangular plate with a central shaft hole and three inward radial slots. Make the result a valid editable precision CAD solid.
