I did not create the boxes. Original Models found here

Box Modifiers:

Refer to video for walkthrough..

• Load modifier- Formatted as STL
• Reset Modifer Coordinates
• Scale as needed and set modifer to filament color
• Adjust Z Height of modifier for color layer - I use 2 Layers until .40mm layer height
• After slicing your pattern will the original model color and modfier color

Prebakes:

Refer to video for walkthrough..

• Open prebake and slice to preview the design
• Load in your model and copy the modfier parts from Plate 1
• Paste into your object and adjust the X-Y-Z of the modifier
• Your Z Height dictates your color height. It can be adjusted layer by layer with the move tool.

Tips:

Scale Object before you copy the modifiers over

Happy Slicing!
