Derived from thingiverse.com/thing:24282

I have made a new housing for an old 540 motor I borrowed. The new housing fits a 540 motor and has feet for mounting.
I have made a video with the 540 running the fan. The 540 is old an defect so it takes 20 amps of my powersupply and drops the voltage to around 3-4V! But it makes a lot of noise though!

Edit 20/3/2013:
New impeller unit with screw for fixating the wheel on the axis of the motor.


Printed it without support, PLA.
The wheel is designed to fit a 3mm shaft.
Mount the motor in the housing and push the wheel on the motor, fixate with screw and m3 nut.

Could you please post the housing source?

Done :-) I use autocad, so it's .dwg

I have noticed the blades appear to be reversed.

Okay... Could you say if they are reversed or if you just think that they are? But no matter what, this is just a remix of another project, so please contact the original creator to see if he want's to redo it...

Siren_impellerMartinuntitled.stl is the new file. (they are both updated on 20/3/2013) so I had to open them both. Maybe its easyer for the users if the old version is deleted from thingiverse. Or am I missing something..

By the way, nice upload :-)

Ohh. But the one you refer to is for fixating with bolt and nut. The other one is just pushed on the shaft. I have not tried to print the one you refer to, but only the one that is pushed on the shaft.
I just havent had the time to print and test the one with bolt and nut yet. So would not delete the old file yet...

Ok, i printed the parts but i need the wall thickness to be a bit thicker. Also tried to have the Siren_impellerMartinuntitled.stl printed but half way I found out it was printing a big solid cilinder.. and this was not support material.

anyway when i have some time again I will try some more.

That sounds a bit strange.. I have tried to slice the model and viewed the layers.. The model seemed okay, but I will try to print it in a few days.
