Prusa i3 MK2 Filament Cleaner

I went through a lot of designs which can be attached to the printer and it cleans the filament as it enters the nozzle using  sponge. All the dust gets collected thanks to the sponge! But what i didn't like about majority of the designs is that you have to remove the filament and then put it through this cleaner! So I designed one which can be attached to the printer directly without the need of having to remove the filament! Also it's a very small and a simple print! 

Enjoy!

Happy Printing ^-^
