The prompt
Create a 3D CAD-style children's 12V electric ride-on tricycle inspired by the classic rounded Vespa-style children's scooter shown in the reference image. The overall exterior shape should be cute, compact, rounded, and retro scooter-like, with: - one front wheel with steering handlebar - two rear wheels - front leg shield / front fairing with smooth rounded curves - rounded scooter body - comfortable child-sized seat - rear storage compartment / luggage box - simple classic scooter proportions - smooth plastic body panels - child-friendly rounded edges The vehicle must have exactly THREE wheels: - one front steering wheel - two rear wheels - right rear wheel connected to the 12V gearbox drive - left rear wheel free-running without a gearbox drive INTERNAL CHASSIS: Create a separate strong internal metal/mechanical chassis underneath the plastic body. The plastic body is only an exterior cover and must not be the primary load-bearing structure. BATTERY: Place a 12V rechargeable battery compartment underneath the child's footrest area. Create: - enclosed battery tray - removable battery cover - multiple bolt holes - adjustable mounting slots/brackets - cable routing openings - enough clearance for different common 12V battery dimensions Do not assume one exact battery size. REAR GEARBOX: Create a mounting area for a 12V children's ride-on gearbox near the rear axle. Include: - gearbox mounting brackets - bolt holes - axle supports - right-wheel drive connection - left wheel without gearbox drive - adjustable mounting interface so the actual gearbox dimensions can be fitted later SEAT: Create a child-sized scooter seat with: - hinged seat - storage compartment underneath - pull handle underneath the rear of the seat for opening the storage compartment - charging port opening inside/under the seat - bolt mounting holes - removable seat for maintenance STEERING: Create: - one front steering wheel - steering column - classic scooter-style handlebar - front windshield/windscreen - strong steering mounting structure HANDLEBAR CONTROLS: On the LEFT side of the handlebar: - small horn button - small music button - separate small button caps/pressers - mounting holes for the buttons DASHBOARD: Create openings for: - oval MP3 music player - ON/OFF button - forward/reverse switch - accelerator pedal - small control buttons Include mounting lips and bolt/screw holes around each component. STYLE: The overall body should closely follow the rounded classic Vespa-style children's scooter appearance from the reference image, including the rounded front fairing, curved side body panels, low seat, and rear storage box. Do not include a remote control or wireless remote receiver. Make all mechanical components, mounting holes, battery compartment, gearbox mounting area, seat storage, steering system, and body panels clearly separated and editable in the CAD model.
