The prompt
Create only the chassis/enclosure of a functional robot vacuum. Do not model any motors, wheels, brushes, fan, electronics, sensors, or batteries. I already own those parts. Make the outer body a perfect 300 mm diameter circle, about 70 mm tall, with a 3 mm wall. Make a removable top cover. Inside the circular chassis, create mounting spaces for 2 BO motors (70×22×25 mm), 2 BO wheels (65 mm diameter), 1 BO motor for the main brush, 2 N20 motors (30×12×10 mm) for side brushes, a 50×50×15 mm blower, 75×40×20 mm 2×18650 battery holder, 43×43 mm L298N, 45×18 mm Arduino Nano, HC-SR04, IR sensor and small speaker. Do not create these components; create only their mounting holes, cavities and clearance spaces. Add a removable rear dustbin with a hollow 0.8–1 L capacity, removable lid and removable filter compartment. Add an enclosed airflow path from brush area → dustbin → filter → blower → exhaust. Add removable motor mounts, wheel openings, battery compartment, electronics mounting holes, sensor openings, cable channels and screw bosses. Keep everything inside the perfect circular 300 mm outer boundary. Make the chassis practical for 3D printing and assembly. Use separate bodies for chassis, top cover, dustbin, lid, filter frame and battery cover. Avoid complex Boolean operations. Exportable as STEP/STL.
