The prompt
Design three separate 3D-printable mechanical components using PETG plastic. Output them as STEP files. Component 1: Main Sorter Chassis - A rectangular machine chassis measuring 420mm wide by 220mm high by 220mm deep with a 3mm wall thickness. - Include a large rectangular docking bay cutout at the bottom center measuring 398mm wide, 105mm high, and 220mm deep. - Add a 23mm by 11mm rectangular cutout on the lower right front face for an OLED screen. - Add a 10mm circular cutout directly next to the screen cutout for a USB-C cable. Component 2: Top Card Hopper - A vertical rectangular card hopper measuring 70mm wide by 95mm deep by 120mm high with a 2mm wall thickness. - The top face must be completely removed so it functions as an open box. - Add a vertical rectangular slot down the center of the front face measuring 35mm wide and 100mm high. Component 3: Internal Motor & Conveyor Mount - A flat rectangular mounting plate measuring 380mm wide, 100mm deep, and 5mm thick. - Add four NEMA 17 stepper motor mounting hole patterns spaced evenly across the back edge. - Add a central rectangular cutout measuring 60mm by 20mm for an ESP32 logic board.
