The prompt
Design a flat, rectangular mechanical adapter plate to mount a standard retail ATX power supply into an HP EliteDesk 800 G1 tower chassis cutout. The overall outer plate dimensions must be 150mm wide, 86mm tall, and 4mm thick to ensure a rigid 3D print. In the center, create a large rectangular cutout measuring 134mm wide by 70mm tall to allow full airflow and space for the power supply's rear fan grill and power switch. Add four unthreaded mounting holes through the plate with a diameter of 4mm each, positioned precisely at the corners to align with standard ATX chassis screw specifications. Ensure all structural edges have a 2mm fillet to prevent stress fractures, and optimize the geometry for flat-bed FDM 3D printing with zero structural overhangs.
