80mm Fan Shroud
thingiverse
I needed more than a wimpy 40MM fan on top of my Pi. the only thing I had was a 5 volt 80MM fan. I threw this together really quick. I like it. I will fit most of the cases I have seen that provide a space for a fan on top of the case. I am going to use it with this case: https://www.thingiverse.com/thing:2407893
