1. Structural Design: The box body and lid are integrally 3D-printed, with a built-in hinged joint on the rear side. Front and rear mounting slots are provided, allowing the box to be secured either with M3 screws or snap‑in latches, ensuring easy assembly and disassembly while maintaining neat, uniform closing gaps.

2. Cavity Specifications: A rounded‑corner square interior offers a well‑organized space with no dead angles, effectively preventing dust accumulation in corners.

3. Practical Applications: Ideal for conveniently storing small items such as screws, earrings, tiny components, fish hooks, and other loose parts; it provides dust‑proof and anti‑loss protection and can be placed in pockets, tool bags, or on desks.
