Ceiling mounted dust and fumes extractor arm

I just mounted an extractor arm above my bench connected to a duct fan blowing air through the wall. Turned out very nice, I can see most of the smallest dust disappear and also the superglue fumes!

The arm is adjustable with three movable joints and can be put anywhere in the air above the source of the dust or the fumes. The locker double as a sounddamper when vibrating guitars and as a "fume hood" for stinky stuff when the loose sleeve on the ventilation hose is removed from the fan.
