I wanted to print a B&W version showed on the design photo of the original version, but without painting or anything, so I made an inner part and an outer part which can be printed over the inner part.

Here is how I printed it:
I printed the inner part first, but I removed the GCODE-s from the end of the .gcode file which turn off the heatings, so that the inner parts adhesion won't release and I can change filament.:
M104 S0 ;Turn-off hotend
M140 S0 ;Turn-off bed

After changing filament I printed the outer shell part onto the inner part. And basically that's it. I used glue on bed, and skirt, no brim, and of course I removed the first parts skirt from bed before starting the second part.

**UPDATE 2021.01.08**
I updated the .stl files, because after printing it with other color than b&w, it turned out the inner shell had to be changed to a wider piece to correctly cover the design from above.
