The prompt
Create a 3D spur gear with 20 straight teeth. Outer diameter 44 mm, center hole diameter 10 mm, thickness 10 mm. Add a 20 mm diameter hub on one side, 4 mm high. Use a standard involute gear tooth shape if possible. Keep the center hole open through the entire part. Show the result as an editable 3D CAD model with exact dimensions.
