The prompt
A rectangular 2-wheel robot chassis for 3D printing. Overall outer dimensions: 120mm long, 80mm wide, and 45mm high with a wall thickness of 3mm. Open top box structure. Include an internal battery compartment sized 70mm x 40mm x 20mm in the center. At the rear, add two side cutouts for small DC motor shafts (20mm diameter mounts). On the top inner shelf, add a flat mounting plate with four M2 screw holes spaced 20mm x 16mm apart for an Adafruit BNO085 IMU sensor breakout board. Front face features a flat mounting flange with two 4mm holes to attach a front mower attachment.
