It is a remix of my original magic box. I tried to add a different color text on top of the box casing. Provided slicer model for Prusa MINI+ uses two extruders and Single Extruder Multi Material option. 

To make it easier to change the filament, I added an M600 custom gcode for changing the tools and the wipe tower. 

Both options require a small modification of gcode in the current version of slicer (v2.4.0). I removed the M600 code after the start sequence and the unnecessary wipe tower layer after printing the model. Optimized gcode is included.

A tip for better slicer settings is welcome.
