Filament Dust Filter

Just another dust filter for 1.75 filament.

I do not like printing the hinge in place as it gives unnecessary bulk to the hinge. I am using simple pin that I cut to proper length.

Holes for hinge pin need some cleaning with 1mm drill. I used pin vice and went slowly. Otherwise the plastic can melt.

There is one "blind" hole - the pin should be pushed in with force. No need for glue.
