Centrifugal Fan Housing and Impeller

thingiverse

The original intent was to use this to blow the dog and cat hair off of my desk. I stripped down an old Bissel hand-held vacuum to use as the motor. This thing throws off so much air, though, I don't think it's a good idea to use it indoors. You may have noticed that some of the blades are chipped.. Well, when testing it, I decided to put a marble inside to see how catastrophic the failure would be. This was to determine whether it would be safe indoors. The failure was not catastrophic, but I had considered using a "screen" over the inlet hole in case of a failure so that parts do not go flying everywhere. USE THIS AT YOUR OWN RISK! That being said, my impeller blade is pressed onto the shaft of the old vacuum cleaner motor. There are no supports needed, and the screw holes in the cover are unnecessary in my opinion. The housing snaps together quite well without any screws.
