Real nice fan, will need as nice a cover though. ;)
i want to make a nicer cover, but i lost the design files when my HDD crapped out. perhaps when i get some free time i'll redo the whole thing.
nice print btw.
It's a nice design already, but if you are considering changes... ;) The screw positions could be shifted a bit to alow a standard "square" cover like many that can be found around Thingiverse.
