So after almost a year I finally made a smaller version of my rolling top box:

This is not a rescale but a complete remake due to complexity of moving parts.
It has small improvement in design for easier assembly.
All parts fit Prusa MINI and similar sized printers (18x18cm).
You might will have to disable skirt/brim for the rolling top to fit tho.
You can slide the rolling part in after everything else is in place from the slots in the bottom and secure with the pins afterwards (when the drawer is fully opened).
