I measured and cut foam board to go around the fan, then I got the glue gun out and glued it together.
I added weather stripping to the edge so turbulent air inside the hood would not blow down.
I got some drier hose and connected it into the hood.
Looking like a giant slinky, it sits on top of the hood with the window end propped against the wall.
When it is time to extract fumes I put the window end into the sliding window. The idea is that it is put in the window and the window slides shut jamming it in the window.
I made the window end by cutting some hardboard a little smaller than the open window space. For some extra insulation I glued some foam board to it. I also added some more weather stripping so that there are no cracks when the window is slid closed.
So far when placed in the window there does not seem to be much of a drop in temperature in the room or at the 3d printer though it’s hard to tell because it is not winter and not minus 30 degrees C outside. Noise level is good.
Will have to wait and see. Now I can get back to some printing.
But it is coming and I moved the 3d printer from it’s summer home (the garage) to it’s winter home (the basement).
I discovered that after printing for about 3 hours in the basement, the air is a bit stuffy even with the window open and a fan in the window. The beauty of the garage was that it was an open space; the negative was it was hot in summer and it would be cold when winter came.
So I thought I would try to create an extraction system for it (like a cooker hood).
I looked on line for fume extraction DIY style and all I could find was exaction fans for soldering irons. These seemed quite wimpy or in some cases very noisy.
Extraction on and ready!
I am not a HVAC engineer so there is no science behind this particular thing. I just built it. The end result is I want it to remove fumes. It should not be permanent because I really do not want the window open all year around for security and heat reasons.
My only concern is that the motors are meant to be used vertically not horizontally.
I bought a window fan extractor for about $30 and hung it on the wall sitting on some shelf angle brackets I already had.
This is what stage one looked like. Then I built a hood around it.
