Customizable foldable box

Customizable foldable box

The model is inspired by the inventions of the renowned inventor Robert Gair, who in 1890 produced the first examples of foldable boxes intended for industrial use. This version is a parametric reinterpretation of the original concept, with numerous modifications aimed at making most dimensions functional

Printing these boxes using this method offers several advantages, notably significant filament savings and the ability to achieve a textured finish on all sides of the model. Once printed, the piece simply needs to be folded along the designated grooves

How to use the generator:

To customize the model, you need to access the MakerWorld website in your browser or use Bambu Handy on your phone. Bambu Studio currently does not support in-app customization. Once on the website, simply click the customize button to open the generator. Then, you will only need to enter the desired dimensions, replacing the preset ones in the left column, and then press generate. Once satisfied with the result, simply download it in .3mf format and open it with Bambu Studio. I highly recommend downloading and using the print profiles (.3mf) uploaded on the model page

Printing tips:

For successful printing of the box, the print bed must be thoroughly cleaned and calibrated

Editable variables:

• Side a mm: modifies side “a” (see cover photo)

• Side b mm: modifies side “b” (see cover photo)

• Box Height mm: modifies the height of the assembled container

Recommended print settings:

• 0.4mm nozzle (NOT compatible with 0.6mm and 0.8mm extruders)
• PLA Basic Bambulab or PLA Silk+ Bambulab. Other filaments tested at your own risk. DO NOT use PETG
• A textured print bed will enhance the aesthetic of the finished product

The model was created using an A1 mini and is compatible with all mid-to-high and high-end 3D Printers. The project was developed entirely in Fusion 360 and required approximately 65 prototypes to ensure maximum functionality and durability

No supports are needed, and the model prints completely flat
The model must be folded manually after printing, keeping the side that was on the print bed facing outwards

Folding steps

Personal note

The creation of this project was particularly challenging; it was my first time designing an entirely parametric model, and initially, I had no idea how many formulas would be needed to make it function correctly. Despite this, I am very satisfied with the final result. After numerous attempts, the tolerances are now correct, and the resulting boxes have a solid and decidedly professional appearance

Updates list:

V1- 21/12/2025

V2 - 30/12/2025:

improved closure system

V3 - 21/01/2026:

complete model redesign to optimize it and make it more stable. Additionally, some generative parameters of the closure system have been modified, which now build the model on geometric bases, resulting in a perfectly flush fit and a much more robust closure. The issue of oblique walls, which were slightly inclined even at the top, has been corrected; they are now almost perfectly perpendicular and coplanar with the closed lid

V4 - separate model:

a 2-color version with the typical gift box shape is available on my profile
