Bộ lọc bụi dây tóc Bowden

I have a lot of issues with dust collecting on my filament spool because I rarely use the printer so I made a small dust filter that connects directly at the entry of the extruder with a bowden tube. This is made for a Creality Ender 3 Pro, but it could be adapted for any type of printer easily. The bowden tube inside the filter is in 2 parts: one at the entry of the filter until the “cage” and the other starts at the end of the “cage” and leads into the extruder mount. It's done like this so the filament does not rub directly on the printed plastic. For the filtering stuff, I used a few strands of material from a furniture duster, but you can use almost anything.

Happy Printing!
