Parcel Delivery System solution

In this challenge, a straightforward solution is demonstrated through the model. The auxiliary door serves two purposes: preventing large packages from entering and enabling expanded packages to be removed easily. Accessible only from the back, the door cannot be opened when the drawer is closed. When fully extended, the auxiliary door aligns with the drawer's "ceiling." Each drawer features a sloping sheet metal plate that assists in parcel removal and ensures drawer independence.
