BabyNES Raspberry Pi B+ case lid with vent holes

I like the nin-tastic, but with the new B+ pis it doesn't fit. http://www.thingiverse.com/thing:449877 works with the B+ but doesn't have the vents in the top which I think really help with cooling.

All this is, is a remix of the lid with the vents added.

Edit: I flipped the object in the stl file for those who don't have applications to do it. Now the stl is flat for printing.
