Prusa Core One Fan Shroud

I noticed my Core One's back fans were pointed directly at a wall with not a lot of room for air to flow. This shroud redirects the exhaust air upwards so you don't have to worry about how close your printer sits near a wall. 

You will need 4x M3 screws to attach the shroud to the back of the machine. Any length will work but I had 10mms on hand for mine. I didn't use supports but feel free to do so if you would like.
