Filament dust filter (1.75mm diameter)

###PURPOSE Dirt and dust particles on the filament gather over time and cause extruder blockages. This practical answer fixes this issue. To do it, simply print out this dust filter and put a piece of sponge inside it around the filament. It will work! ###FILES You must print the __dust_filter_out.stl__ and the __dust_filter_in_x.xxmm_tolerance.stl__ file. You can pick the right tolerance for your specific situation. ###SUGGESTIONS - If you're printing slowly with a 1mm layer height, consider using the **0.0mm** tolerance or the **0.25mm** one. The first option may require some sanding but will give excellent results as you can control the perfect amount of friction you desire. On the other hand, the 0.25mm tolerance should work perfectly out of the box. - Printing quickly with higher layer heights might reduce printing precision so you'll likely need more tolerance (from **0.25mm** to **1.0mm**). - I'm not sure why I made versions with higher tolerances (from **1.0mm** to **1.5mm**), but if you really want them, they're here for your use!
