Fine dust filter

Fine dust filter for my new Ultitop Cover from (http://www.3dprinterstore24.de/3D-Drucker-Bauteile/Drucker-Abdeckungen/Tueren/Ultitop-1-2-Drucker-Abdeckung-fuer-den-Ultimaker-2-COVERING-BS::191.html)

I printed some parts with the new filter and it works great, the smell is much better now afer a print over 2-4hours.
