Re: [sudo-discuss] mx brown switches in salvage

we have a duct fan, it's under the laser cutter to the left of its cart last i saw it, it's a beige and blue metal box the size of a small TV/VCR combo, and it has two 4" duct things on the back. It would need some modification to work with the exhaust duct we have (cardboard and duct tape or something from the hardware store or a cut-up plastic bucket) and then its inlet can be ducted to our acrylic fume hood box thing, or to whatever we're trying to ventilate. also don't forget someone should go on the roof and reposition the top of the duct in the skylight thing so it's centered over its hole, so it doesn't leak back into the room like it does now.
