Multi level tool box for printers with a 4040 extrusion. This one designed around the Creality CR-6 SE (left side). Plenty of room for nozzles, memory cards, you name it. Some support needed. Use a length of filament for the hinge pin. Top and bottom sections can be aligned and glued using the locator pins.

Note, the 4040 extrusion profile will be snug. You may need to sand it down a bit, depending on your printer hardware or slicer settings.
