Power supply fan air duct for Alfawise U20

This is an air duct to redirect the U20's power supply hot air fan to the enclosure side openings...

Better to put the hot air out than just leave it inside the enclosure!

Just use an M3 screw and a M3 big diameter washer to fix it in the existing threaded hole. This hole is not allways in the same position. That's why this is ajustable with the washer.

Two models: choose yours! :)
