Filament Cleaner (Both 1.75mm and 2.85mm versions)

Keep dust and debris out of your hotend with this filament cleaner.

I have some very old filament that has quite a bit of dust on it that I want to avoid getting into my printer. I designed this simple print which will allow you to insert a sponge into the canister and then push your filament through. Doing so should really help make sure the only thing going into your printer is the intended filament.

Went through a few revisions and am very happy with the end result. There are two versions with one for 1.75mm and one for 2.85mm filament.

I printed at .2 layer heights in PLA and the threads worked very well.
