It's a pretty straightforward box. I followed https://www.youtube.com/watch?v=0Sla-vIsvh4 to add a colored inlay to my box:

• Arrange both models in your slicer so that the inlay fills the void in the top
• Slice and print just the inlay. You might want to tweak your slicer settings to print a little slower for better build plate adhesion
• Once the first print is done, quickly start heating your build plate again to maintain adhesion
• Slice and print the top in the correct position with zhop set to at least 0.3 mm (assuming your initial layer height is 0.2 mm). That'll push the print head up to 0.5 mm, which should just clear the inlay which is 0.4 mm.
