This packs a punch! Thanks

could you please post your cad-files?
i would like a smaller intake with integrated guard and smaller holes on the backplate so i dont need nuts.

I'd print one soon..
like to know how it sounds..
good design!

This idea really blows... Litterally. :-)

I printed one last night. Came out perfect! and works well!

Here ( https://vimeo.com/66955794https://vimeo.com/66955794 ) you fine my print alive! :)

Sorry for the bad video quality; ...but the fan works very well!

With only 1.5V I obtained a 4.6 m/s airflow.

lol, that's awesome! can't really see what kinda motor you have there, but it must be more powerful than mine. I imagine at 1.5V it's current draw is pretty high...

Hi ghostling, thank you for the model. ;)
The motor is something like this: http://goo.gl/KFpNOhttp://goo.gl/KFpNO ...pretty standard

The current absorption, just tested, is 0.4 A.

I raised up the voltage to 4.5V (I've not measured the current), and the airflow was really powerful: 30 km/h! ;)

so 8.33 m/s @ 4.5V... i can live with that. xD

what instrument did you use to measure the air speed?

:D yep! you can even stop breathing: the fan does it for you! :P

The instrument is this one: http://goo.gl/BzIvQhttp://goo.gl/BzIvQ

Awesome, do you have any vids where we can see how it blows?
