Laser Exhaust without enclosure

Hi all. I am about to get my laser going on my longmill 30x48 and am trying to figure out how to exhaust it. I have a good inline fan i can use and a easy path to exhaust it outside. My issue is how to keep the exhaust hose above the laser, what do i attach it to? Is there a bracket available like the dust collection mount? What does everyone do for this part of the setup?? I do not want an enclosure at all. I like my machine to be open.
