In some spare down time at work I have been ever so slowly making a 4 cylinder engine.  So far I have the bottom end rotating assembly modeled, and in an assembly with motion.  I just finished the crank girdle, and next would be the oil pickup.  And going with the detailed model I am shooting for, Id like to have the screen.  Any ideas on that?

I know there is a perforated appearance, but I would prefer something that is really modeled.  I was thinking I could just extrude a grid type shape.
