Filament Dust Filter (Foam)
thingiverse
This is a filter I made to keep dust off of my filament. Scale to 140% or more. Supports Required. *IMPORTANT* *To give the "hinge" more flexibility heat the print with a lighter or heat gun prior to clipping it shut on the filament. * You will need a small cylinder piece of foam (or cube with sides shaved works fine) as the filter for the dust, simply cut a slit in the foam down to approximately the middle (you could probably cut it completely in half and have no problems but I have not tested).
