Filament Filter and Clip

thingiverse

I've been printing non-stop without any nozzle clogs since discovering these devices. They're incredibly effective at keeping dust out of my printer. To make them work, simply insert a small piece of sponge into one end and add a single drop of cooking oil. Then, thread the pointy end onto your filament after trimming it to size. I recommend printing one of these clips for each roll of filament you use. Not only do they prevent nozzle clogs, but they also serve as a convenient clip that can stay attached to your printer at all times, eliminating the need to constantly fiddle with it.
