Filament Dust Filter

I wanted to be able to mount the filter even after the filament was already loaded, so i made it screwable, the filament will be guided perfectly.

• print in given orientation and  put some filter material in the body parts
• you can use double sided tape to glue the filter material in the body parts
• a little grease makes the thread run more smoothly  

if someone needs a filter for 2.85mm, comment or dm.
