Thanks to @VisualReversal for this great solution. I needed to reduce the length of the left waste bin, from 170mm to 160mm because of my webcam installation.
As the org. stl-files (via 3mf) had only textured walls I imprinted a light hex design.
Then I divided to three files each box for MMU2-printing purposes. You can put them together in one print and change color if you want, or make uniform color.
If you want 170mm on the left box, just mirror it.
Printed on MK3S+ with MMU2s in PETG, 0.3mm LH. Orange Prusament and black Fiberlogic.
