We'd love to hear from you if the print was successful.
MakerGear M2 Ducted Fan Mount
There are a lot of alternative hot-end fan mounts for the MakerGear M2 that try to increase airflow where it counts, but most of them require a modified mounting assembly for the hot end. This one goes on just like the standard mount -- in front, and is still able to pivot out of the way for access.3D printer parts and enhancements

The duct looks scary thin, but is quite strong and prints easily on an M2. In PLA 25% filled, it only uses 10g. It mounts using the same screws and nuts that came with the M2.
Incidentally, yup, that is it being used to print a copy of itself in the first photo. Why? Well, I printed the first one before I had the attachment and the second one (as you can see) after. The second one is a much nicer print... which was the whole point of doing this. I actually have two M2s, so neither copy of this mount will go to waste. ;-)
The photo of the cup is of http://www.thingiverse.com/thing:690176 , printed on my MakerGear M2 after installing the ducted fan mount. This is a tiny wine glass, with a long stem that's around 2.25mm diameter -- which would have sagged and probably caused a print failure with the standard fan mount. Printed in white PLA at 0.25mm, 8% fill (there's fill in the base, stem, and lower portion of the cup), 50mm/s.
