40mm Blower Fan to 40mm Axial Fan Adapter

Simple adapter to mount 40mm blower fan to a regular 40mm fan slot. I had some 40mm blower fan around and was curious to see if these blower fan will perform better than the conventional axial fan in cooling the feed stepper motor.
I have test printed it and everything fits fine, however I have not test its cooling effectiveness.
