Introduction

ModuBox is a practical and adaptable storage solution designed for use with the Gridfinity system, offering a flexible way to organise your workspace. The modular design allows users to configure storage based on specific needs, whether for tools, parts, or other materials.

A key feature of ModuBox is its compatibility with the Gridfinity grid system, allowing it to fit seamlessly into existing setups. It can be 3D printed in smaller sections, making it accessible for printers with smaller bed sizes, and these sections can be assembled into larger units based on the desired grid size.

ModuBox's stackable structure makes it a space-saving solution that can grow vertically to help maximise available space. Each unit is designed to stack securely, providing efficient storage without taking up unnecessary room.

The design prioritises functionality and durability, ensuring a long-lasting storage option. The modular setup means it can be easily expanded or adjusted as storage requirements change over time, providing flexibility for evolving needs.

In addition to its integration with the Gridfinity system, ModuBox can be used for a variety of general storage applications, offering an efficient and organised way to store small items like tools, electronics, or craft supplies.

Printing Guidelines for ModuBox

To ensure the best results when printing your ModuBox, we recommend the following settings and considerations:

• Layer Height: Use a layer height of 0.15mm to achieve a fine surface finish and precise details.
• Infill: Set the infill to 50%, balancing strength and material usage.
• Wall Layers: Use 2 wall layers for a solid structure that maintains the integrity of the joins.
• Support: No automated support should be needed as I have built them into the files (Printable) for maximum quality and ease of removal, as well as minimising its impact on the joints.
• Bed: Use smooth/engineering build plates for accuracy and finish consistency
• Material: Anything really, I use Matte PLA mostly, although for the skeleton, ABS/ASA would be a great material to use.
• Wall generator: I use Arcane wall generator, this is largely your choice, but the joints are printed better IMO with this generator.

Assembly

Main Assembly:

See BOM folder for different configurations

Assembly order:

Assembly instructions incoming, but for now, see BOM:

1. Base corner (x4)
2. Base rim (x1)
3. Base grid (x1)
4. Base sides (x2 regular, x1 with latches, x1 with hinges)
5. Lid edges (x2 regular, x1 with latches, x1 with hinges)
6. Lid rim (x1)
7. Lid grid (x1)

Change log

• 26/04/25:
  • v1.2 released!
    • Adjusted tolerances
    • Improved hinge design
    • Added centre hinge type
    • Added full example assemblies
    • Added missing files for hinges and latches (fixtures)
• 04/10/24:
  • v1.1 released!
    • Removed all split dovetail joints, after a lot of head scratching, I conclude they didn't work. Improved joints on the top edge of the box and the corners for taller boxes.
    • Adjusted all tolerances, This now fits better allowing less internall stress buildup, leading to lid and face warp.
    • Improved the 'snap' of the panels, so they are easier to put it, hold the skeleton in place and make a more satisfying assembly experience.
    • Note, All v1 parts are incompatible, so I put them in a legacy folder incase someone still need to expand their v1 boxes etc.
• 08/09/24:
  • Updated the top edge tolerances (too tight, causing some assembly failures)
  • Reversed change log order (newest first)
• 03/09/24:
  • Added BOM (as a CSV file) for 5x4x2 and 5x4x3
• 31/08/24:
  • Updated skeleton and panel parts for both step and stl formats. 
• 28/08/24:
  • Added graphical BOM for single height in description
• 27/08/24: 
  • Added BOM (as a CSV file) for 5x4x1 box
  • Updated latch parts “Latch top edge RHS” and "Latch top edge LHS"
  • Updated Hinge part “Lid edge”
