This filament filter is designed to hold a 20x20x20mm filament cleaner \"sponge\" from Voltivo at the filament entry point of an Original Prusa MK3. But you can use any other sponge with the same size.

Since it significantly increases the height of the moving tool (by 3 cm) you should be careful when printing tall objects because it may crash into the filament spool or any other additional extensions you may have placed there. I recommend using it with the filament spool not over the printer.

Print Settings

Print it upside-down and with supports only over the build plate.

Post-Printing

Place the sponge inside with the correct diameter hole.
