Working Squirrel-cage fan (centrifugal fan)
thingiverse
Uses standard 5V DC motor (one shown is from digikey part number P14355-ND) which slides snug into the slow and wire holes are aligned. Give a good amount of air for blowing small projects. Video of operation can be viewed on YouTube:https://www.youtube.com/watch?v=2ef0BfOs4LQ Instructions Updated! Sorry, I forgot to upload the flat round plate that glues to the bottom of the fan blades; this is now uploaded as CentrifugalFanBladesRoundPlate.stl. Sorry for confusion.. Pretty straight forward. Printed using 3mm ABS on a PrintrBot with heated bed. 0.4mm layers. Tried to make the fins as thin as possible, but you can see in the last photo my first attempt caused filament snot everywhere, so the 2nd revision I make the fins a little thicker (1.2mm). Next revision I'm going to try to embed a couple different color LED's (surface mount) to make it pretty inside when it operates.
