Fan shroud for stepper drivers (Anycubic i3 Mega

This is a redesign of a model that I found here.  I thickened up the walls because they were so thin that they cracked and broke as I attempted to check it for fit.  Also I tried to improve the airflow. I printed it with a brim because it's tall and I didn't want it to fall over.  Also I didn't print with supports because I didn't want to break it while I was cleaning it up and my machine is good with bridging.
