Stackable filament storage

Hello, I design some stackable filament organizer storage. I have gap between the cabinet and the desk and i want to storage there mine filament(i don't have much space in room). On photos u can see filament rolls with small drawer or just box with filament. U can storage new box with sunlu filament or bambu lab refill cartons box. The black one is printed with abs but i have too much issues with printing it so i print next storage level in Petg.
