U1 Fan Deflector

U1 Fan Deflector. This one makes sure the fan is circulating the air not blowing on your part cooling one side more than the other. It pops on and off easy so use it when you like and just pop it off when you don't want it. NOTABLE THINGS: stick with dull color, black or grey. As bright colors can set off the A.I. detection. Also, it is not made to be a pressure fit, it is made to stay in and be able to come out. If you want it to be permanent up the size 1% and shove it in there. It is a small part and different filaments have different shrink rates. You may have to resize depending on what your using.
