50x15 radial to 40mm axial fan adaptor

just a simple adapter I made by editing http://www.thingiverse.com/thing:2044285

I wanted to put a radial fan on my malyan m150 hotend cooler.

If you print it please let me know how it works for you and what you use it on.

edit
50x15_radial_to_40mm_axial_fan_adaptor_3.stl has counter sunk holes to allow the use of stock bolts and thickened end where the fan locks in to strengthen it.
