3d printer filter from dust with ptfe bowden connection 3D model

Hello, i made this part, becouse i wanted to clean my filament, durning the print. Its mounted after extruder and before heat block, so if extruder gears are to tight seatled (that make dust that com with filament into tube, and then directly into heat block, and make quality of print worst, also can cause jam).

The construction of filter allow to mount it fast.

Also there is possibility of use 2 filter:

• one to remove dust (with dry sponge),
• oil old filament (with sponge wet with oil) - especially for ABS filament.
