There is some debate if a dust filter is necessary or useful for a 3D printer. I honestly don't know the answer, but I prefer to not have dust in my extruder.
In the first weeks of printing with my MK3 without a filter I experienced a jammed nozzle, after I installed a filter it never happened again. But this could of course be a coincidence. In one of the pictures you can see the dust this filter has filtered in a few weeks and I am not printing very often.
Simply print the part in 0.1mm layer height and put a small piece of sponge inside. Push the filament through and that's it. Some say that a drop of mineral oil on the sponge will get even more dust but I don't want to mess around with oil near the hot end.
The M14 thread between lid and body has been modified to work right out of the printer, for me even a 0.2mm layer height worked great.
If you feed the filament through a PTFE tube, there is also a small 4mm hole in the lid for a better fit.
~Update 19.01.2019: I added a modified lid which holds a bowden tube if you are feeding the filament from a drybox, I also added the step files if you want to modify it yourself.
Update 23.01.2022: Extruder cover for MK3s added, simply replace stock cover.
Have fun!
