What it does

  • Parametric design, customize dimensions to fit your exact storage needs
  • Integrated living hinge connects lid to base in a single printed piece
  • Friction-fit inset lid keeps contents secure without latches or fasteners
  • Perfect for organizing small parts, tools, electronics, or craft supplies
  • Flexible design works best with PETG and other semi-flexible filaments

This customizable rectangular case offers a practical solution for organizing and protecting small items. The parametric design allows you to adjust the interior dimensions to match your specific storage requirements, making it ideal for everything from electronics components and hardware to crafting supplies and travel accessories.

The case features an integrated living hinge that connects the lid to the base, eliminating separate parts and creating a sleek, functional design. The inset lid uses a friction-fit closure system that holds securely without additional hardware. The flexible hinge mechanism is optimized for semi-flexible materials like PETG, though the design can be adapted by adjusting hinge thickness or length to work with other filaments.

Whether you need a protective case for delicate components, a sorting box for your workshop, or a custom container for on-the-go organization, this versatile design adapts to your needs. The single-piece construction means no lost lids or loose parts, everything stays connected and ready to use.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
