I use a Stuter/Livinbox A90-520 20-bin organizers. These are great for mounting on the wall to create extra space where there might have been some excess. They come with nice polystyrene dividers, but not enough of them for my uses.
If your printer is reasonably well dialed-in these should fit snugly and not move. They actually fit a bit better than the OEM ones.
Printer: Prusa MINI+
Profile: Generic PLA on 0.20mm SPEED
