The prompt
Design a square mechanical base plate for CNC milling. Material: Aluminium 6061-T6. Overall Dimensions: 270mm width x 270mm length x 6mm thickness. Features: 1. Four corner mounting holes: 8.5mm diameter through-holes, centered at 25mm distance from each adjacent edge (hole pitch is 220mm x 220mm). 2. Central clearance hole: 25mm diameter through-hole located exactly at the geometric center of the plate. 3. Four mounting holes around the center for the pivot mount plate: M5 threaded holes (or 5mm through-holes) arranged in a 45mm x 45mm square pattern centered around the 25mm central hole. All edges must have a 0.5mm x 45-degree chamfer. Output as a STEP file.
