The prompt
Generate a 3D model of a roller chain sprocket for metal cutting. The sprocket must have the following exact dimensions: - Number of teeth: 24 - Chain pitch: 19.05 mm - Roller diameter: 11.91 mm - Pitch diameter: 145.95 mm - Outer diameter (tip to tip): 154.20 mm - Total thickness (extrusion depth): 10.00 mm Internal features (Center bore and keyways): - Create a central circular through-hole with a diameter of 38 mm. - Add 2 (two) rectangular keyways to the central hole, positioned exactly 180 degrees opposite to each other. - The width of each keyway is 10 mm. - The total distance measured from the bottom edge of one keyway to the bottom edge of the opposite keyway is exactly 45 mm (each keyway has a depth of 3.5 mm from the edge of the 38mm hole).
