H2C | H2D | H2S 90 Degree Exhaust UP vent

After deciding I needed my vent to run above my printers, I designed this 4" 90 degree exhaust to run up, as I couldn't find one on here. This does not interfere with the automatic louvers. If you're installing several printers on one exhaust, as I did, you will likely need to install an inline exhaust fan to create a small amount of negative pressure so the exhaust from one printer doesn't go into another. Of course, this all goes to a window duct to vent outside.
