Part 6/9:
To allow the user to peek outside discreetly, a sliding door mechanism was designed. A U-shaped rim was glued to a frame and embedded into the window cover, with the door itself fashioned from a piece of plastic that glided smoothly. A fan filter was glued to the back to prevent insects from entering, and a small stopper was added to control the door’s range of motion, ensuring it could be opened just enough for viewing or ventilation.
