A little attachment for ID:3574173. I will post a photo with a 400 mesh stainless steel attached, when the mesh arrives. You can use any filter material you like.
Print the first 15mm with rigid material like PETG, then switch to flexible filament. I've used Sain Smart TPU, since it is quite soft, but not stretchy.
Please note, that this filter might not protect you from harmfull fine dust - it is only intended to keep your workplace clean. You'll might want to reconsider to use an appropiate respirator.
