The prompt
Design a mechanical fan shroud transition duct. The base plate is a rectangle measuring 125mm in width, 242mm in length, and 4mm in thickness, with a base thickness 6mm. From this rectangular base plate, loft a hollow transition over a height of 90mm that transforms into a circular duct. The circular duct must have an outer diameter of 151mm, a height of 35mm, and a wall thickness of 4mm. The entire internal volume must be hollowed out to allow unobstructed airflow from the 125x242mm rectangular base through to the 151mm circular duct. Ensure a uniform wall thickness of 4mm throughout the lofted transition section. there should be 4 mounting screws each corner with diameter 4.5mm spaced 7mm from 242mm side and 5mm from 125mm side
