This is another NEMA14 stepper motor fan mount. I specifically wanted one for my Solidoodle2 because the x-axis motor gets very hot but I wasn't satisfied with the other two things I found on here. One didn't have any holes for the air to actually come out on top and the other was to asymmetric for me.
So, here is my take on it.
I will try to improve the airflow still because even now there is not much coming through. Maybe anybody has suggestions how to improve this without increasing the footprint too much?
I printed it with .3mm resolution and 20% infill (ABS). No support needed.
Just screw the fan to the bottom. To power the fan I used one of the 12V pins on the Solidoodle board. If you want you can add some heat sinks to the sides of the motor to improve cooling.
