Set for Prusa MMU installation to Ikea Lack

As the printer with MMU 2.0 is too high for one box, I was looking for a solution, which enable me to make housing for MMU as well. I saw some solutions where the bottom box was top side down, but I prefer to have small space for the printer, so it can be heated better. Finally I installed MMU separately to the second box with filament spools hanging.
