The prompt
Parametric 3D CAD model of a smart automatic touchless dustbin assembly. 1. OUTER BIN BODY: Vertical cylinder, 240mm outer diameter, 400mm height, 3mm wall thickness, open top face. 2. SENSOR MOUNT: Front-facing recessed rectangular cutout located 25mm below the top rim, sized 46mm x 21mm with dual 16mm circular thru-holes spaced 26mm apart to flush-mount an HC-SR04 ultrasonic sensor. 3. SERVO MOTOR BRACKET: Rear internal mounting pocket sized 32mm x 12mm x 23mm designed to hold an SG90 micro servo motor, positioned 15mm below the rear hinge axis. 4. HINGED LID: Circular top cap, 246mm diameter, 2.5mm thickness, with a 15-degree domed top profile and a 5mm downward lip around the perimeter. 5. MECHANICAL LINKAGE: Integrated rear pivot hinge pins on the bin body and a 40mm control lever arm protruding from the rear of the lid to attach a servo horn link wire for automated mechanical opening.
