Very simple Sanguino 40mm fan holder

I got tired of all these fan holders that were either an entire case, or were meant for fans larger than 40mm.
So, I took the opportunity to create a very simple and basic fan holder for the Sanguino. Check out the pictures, they will tell you everything you need to know.
I positioned the best part of the airflow directly over the Z-axis stepper drivers, because the Z-stepper driver tends to overheat the quickest because it has to drive 2 motors instead of one on my Reprap Air 2.
I hope this is of any use for others.
