The geometric elegance of the crossed legs contrasts with the soft curves of the circular seat, while also fulfilling the functional requirement of storage. The suspended portions of the crossed legs should be reinforced with tree‑like supports to prevent collapse during printing. At the junction between the circular seat and the legs, the wall thickness should be increased to at least 4 mm to mitigate fracture caused by stress concentration.
It is recommended to set the leg inclination angle between 30° and 45°, balancing stability with enhanced visual tension. Additionally, the edges of the seat should feature chamfers (R‑radius ≥ 2 mm) to avoid sharp corners that could cause injury.
