A design for an aluminum frame wheeled suitcase, featuring triangular reinforcing ribs around the entire body. This design is not only aesthetically pleasing but also enhances the toughness of the case, making it more impact-resistant. With a 20-inch size, it is convenient for travel and business trips. The top of the front shell is equipped with a hook for hanging items like a cosmetic bag or small purse, making it both convenient and effortless. The drawings are available in stp and x-t formats, including diagrams of each component, which can be directly produced if the components are identical. Intended for learning and reference.
