Anet A6 inport dust filter and filament guide

It's a remix to my previous model. Version 2.0, reworked to better match and nice look. :)

Filament input port of Anet A6 is made of milled aluminum and have sharp edges, that grind filament. To resolve that little issue, I've made this guide with filter, that is fastened with fan nut.
Place a piece of foam into the funnel to filter dust.
