Forced Air Vent Deflector

After setting up my 3d printers, I discovered they were in the direct line of fire from my forced air system which I wasn't crazy about. I designed a simple shroud to deflect all air the opposite direction so my prints aren't receiving any extra cooling.

I used a .375in / 9.53mm diameter and .06in / 1.53mm depth neodymium magnets purchased from Home Depot to attach the deflector to the vent. They fit tight enough to just pressure fit but I super-glued to be extra sure.
