Filament filter / cleaner (1.75mm)

Yet another filament cleaner.

This is a remix of Mr_3Ds' "Filamentfilter", which I have made it smaller and made the slot spiral. This part can now be printed without support, however the inside top of the dome might look a bit unsightly. This doesn't affect the part or will be visible i the end.

Fits neatly between the extruder and Z-axis lead screw on the Creality Ender 3 Pro.
