ModularBox

Modular storage box system designed with interchangeable parts.

The system uses a grid-based design with separate connectors, corners and panels, allowing different sizes and configurations.

The model includes individual STL files and a 3MF project with my tested print setup, including part orientation, supports and print settings.

Printed in eSUN PET with a 0.16 mm layer height.

Tested printer:
Elegoo Centauri Carbon with a 0.4 mm nozzle.

Optional parts:

• ModularBox-ConnectorMaleCenter is an optional cosmetic part. The standard ModularBox-ConnectorMale can be used instead. It is only intended to improve the visual appearance of central connections and is not required for assembly.

Assembly notes:

Center connectors are only required when four panels meet on the same plane, creating a central junction between GridBase modules.

For vertical or horizontal connections, standard connectors can be used depending on the required rigidity. Additional connectors can be added if a stronger structure is needed, for example by using two vertical connectors or adding an extra horizontal connector between them.

The system is designed to be adaptable, allowing users to choose the number and placement of connectors depending on the final size, configuration and rigidity requirements of their box.

Print requirements:

A minimum build plate size of 200 × 200 mm is recommended to print the GridBase modules.

Larger boxes are created by combining multiple printable modules, so no large-format printer is required.

Important: PLA is not recommended for this box system. Due to its properties, it may become brittle and can break under stress. A more suitable material such as PET, PETG, ASA or similar is recommended.
