This component consists of an internal gear with an external thread.The window regulator includes an electric motor that drives a gear mechanism to raise and lower the window glass smoothly and in a controlled manner. This mechanism is connected to a system of cables and pulleys that guide the movement of the glass within the car door.This part is designed and 3D printed to replace the original gear in your window motor exactly as it was — no modifications or adaptations needed. It fits straight into place, restoring your window to smooth, reliable operation just like the first day.Its optimized geometry allows direct assembly onto the existing cable regulator mechanism, integrating seamlessly with the sliders, return springs, and door guides without any modification to the assembly. The transmission of movement between the electric motor and the cable drive system is thus restored with the smoothness and reliability characteristic of the original design.
