If you try to print it horizontal, it is possible but unless you know how to print soluble support, you would need to print without support at all : "bridging". This is not exactly difficult but it does need some tuning to get it right. A few tries and you should be OK.

Thinking about it, if you try to print it vertical, then it will be much easier : you can use a little support on the air exhaust and it will still be removable. I'd definitely do it that way.
