The prompt

Create a rectangular electronic enclosure box with a snap-fit lid. Outer dimensions: 80mm width, 140mm length, 40mm height. Wall thickness: 2mm. The bottom shell should be hollow with an open top and integrated interior clearance for a breadboard stack. On the top faceplate surface, include two rectangular cutouts for 16x2 LCD screens (each 71mm x 24mm) positioned vertically, and one circular cutout (25mm diameter) below them for an analog joystick. Design a clean snap-fit lip mechanism around the inner perimeter rim so a matching top lid can snap securely into place.
