Well, here it is. I'm sure it's not much to some people, but it was by far the most technical thing I've done thus far. It has 2- 50 cf/m bathroom vent fans. The vent off the fan was 3", so I used 3" 90deg duct brackets to a 3" T, then fed that into a 4" flex duct. I couldn't seem to find any 3" flex duct, so I used a zip tie to snug it down. A few screw in hooks and a hanging wire should give me options depending on the size of plug I'm spraying. Used a 17"x25" febreeze furnace filter.

Nice job, it makes the whole painting process much nicer.

yeah, I did a little spraying, just to get an idea and man does that thing make all the difference in the world!!
