NAPALM's Geeetech Prusa I3 Pro B Fan Duct

After I tried a few other fan ducts for my Geeetech Prusa I3 Pro B, which all did not fit right or I just did not like them ;-) I decided to create my own.

Here it is. Should be easy to print and does not need any additional raft or support.

It did fit on my Prusa with the black extruder, and it fits when using an normal metal extruder. See photos.

I did an extended version of this with two led lights. You can find it here:
