Train Linkage Component

I have completed the modeling of the train linkage component, focusing on achieving a clean shape, accurate proportions, and a practical design suitable for the H0-scale wagon project. The linkage has been refined with the necessary curved sections and connection points while keeping the geometry suitable for 3D printing.

The component is designed as a separate part so it can be printed and assembled easily with the rest of the wagon. I also paid attention to the thickness and positioning of the smaller details to improve printability and durability at H0 scale.
