Gridfinity boxes with fully configurable internal walls.
Walls can be added, moved, or removed directly in BambuStudio to redesign compartments whenever your needs change.

One box, multiple layouts

Walls can be moved in Bambu Studio

Adjustable height in Bambu Studio

Overview

While organizing my large drawers using Gridfinity, and after testing many existing boxes, I decided to design my own solution to push flexibility even further.

This project introduces Gridfinity boxes with removable internal walls.

The concept is simple:

• Print a large box
• Add walls to create compartments
• When a compartment becomes too small, remove or reposition a wall instead of reprinting the box

This system allows you to:

• Add internal walls on demand
• Redesign the inside of a box at any time
• Increase the rigidity of large Gridfinity boxes

Project Content

• 75 different boxes available
• Box height adjustable directly in BambuStudio, from H5 to H9
• Fully configurable walls in BambuStudio:
  • move
  • delete
  • duplicate / add

Each plate includes 5 boxes, covering standard heights H5 to H9.
Boxes are provided by default in H7 (53.8 mm).

All size variations from 2× to 6× are available, resulting in 75 box sizes, not counting the countless possible wall configurations.

Adjusting Box Height Select the box Switch from Global mode to Object mode to display sub-objects Select all sub-objects whose name contains “Top” hold CTRL to select multiple elements Click Move Hold SHIFT and use the blue arrow to adjust the height 📐 To remain Gridfinity-compatible, use height increments of: 7 / 14 / 21 / 28 mm Fine adjustments down to 0.1 mm are also possible to perfectly match existing boxes if needed.

Wall Management

Each box contains 2 or 3 independent walls, fully configurable.

Removing a Wall

1. Switch to Object mode
2. Select all sub-objects named “Wall 1” or “Wall 2”
3. Right-click → Delete
   or press the DELETE key

Moving a Wall Switch to Object mode Select the wall sub-objects Click Move Hold SHIFT and use the red or green arrows 📏 To stay within Gridfinity standards, prefer movements of: 21 mm or 42 mm

Adding a Wall

1. Select an existing wall (Wall 1 or Wall 2)
2. Copy / Paste (CTRL+C / CTRL+V)

⚠️ Note: BambuStudio keeps the original wall name.
Renaming the duplicated wall is recommended to avoid confusion.

Printing Notes

• Prints as fast as a standard Gridfinity box
• Nearly vase-mode printing:
  • two wall perimeters
  • a small detour to create the wall notch

Walls are intentionally simple, making it easy to design custom walls if needed.

Dimensions

Standard Box Heights (7 mm increments)

Wall Lengths (42 mm increments)

(Formula: 42 × L − 2)

Recommended Print Settings

• BambuStudio profile: 0.20 Standard
• Adjustments:
  • Seam position: Back
    → ensures consistent seam placement and smooth circular motion
  • Flush tower: Disabled
    → only 3 color changes, saves time
  • Brim type: Painted
    → painted ears are added on large boxes to reduce warping

Optional Color Changes

• First change at 6 mm to highlight bottom separators
• Second change for the top rim of the box

Wall Types

There are three wall types:

🔹 Solid

• Simple divider
• Runs fully across the box without intersecting other walls

🔹 Half-Height Cut

• Allows walls to interlock when crossing each other

🔹 Ribbed (with alignment ridge)

• Allows one wall to stop against another
• Greatly increases layout possibilities

Walls are provided by default for H7 boxes.

Adjusting Wall Height Select the wall Click Scale Disable “Uniform scaling” (important) Enter the corresponding value below on the Y axis Wall Heights (7 mm increments) (Formula: 7 × H − 9) Height    mm H5        26 H6        33 H7        40 H8        47 H9        54

This modular system is designed to evolve with real use.
