Max Imagination wanted to see if it was possible to fully 3D print a functional remote-controlled drift car, complete with smoke effects, and the answer to that is an astounding yes. Even more surprising is that most of the drivetrain is 3D-printed as well, including the plastic gears and universal-joint axles.
Steering is handled by a servo, while a brushless motor generates the power that gets sent to all four wheels. An Arduino-based R/C system is paired with the steering servo and motor speed controller, which are both controlled using a homemade pistol-grip controller. How does the smoke work? The Arduino activates a small power supply connected to small humidifier modules, which turn water into a visible vapor.

My suggestion IS, you can use a metal or aluminum coated gears to the motor grip for the buzzing sound. There will be not available as such small gears but you can coat the gear in thin layer by using zinc,” said one fan.
