Centrifugal Fan for 3v hobby motor by swirlingbrain

Last crawled date: 3 years, 4 months ago

My hobby motor was a little larger than the original and was 3v. I opened the back end so the motor could hang out the back and made the motor holder size larger. I made the cage shaft hole smaller and longer. I also combined the fan plate to the fan cage so that it was one piece which was OK for my SLA printing.
The fan makes a little noise like a whistle. The fan doesn't make this noise outside the housing. I think if I were to revise it again, I'd mod it so that it doesn't have such a sharp edge inside which may be causing the whistle.
The fan pushes air nicely if a little noisy, tho.
