rc car 3d model

I want to build a car on a remote control. I need you to build me a model from a few parts so that this whole thing works like a pro. First of all, it's important to me that it's 30 x 17 cm. I want you to design shock absorbers for it. I want you to take measurements from Aliexpress. I don't need a design for the car, but I do need a design for the body of the car. I intend to use an engine that has a diameter of 46.6 mm and a length of about 50 mm.In addition, take the dimensions of a standard ESC controller and prepare a place for it. Also prepare a place for the motor. I am also going to combine LED lighting with it. Also prepare a place for a gearbox attached to the motor, the gearbox is electronic so there will be a servo motor there. I want it to look very professional. I want the car body to be durable and strong, I will probably print it in PETG material
