Filament Cleaner Container
This is a simple yet effective filament cleaner. To assemble, just glue small sponge pieces onto each inner side of the container — that’s all it takes for it to function as intended.

For best results, print the model standing upright, with the hinge positioned so that the minor overhangs are handled correctly by your printer (don’t worry, it will print without issues).

👉 I recommend checking the included .3mf file before printing to confirm the correct model orientation.
