I just wanted to share my solution to venting our Glowforge out a window and also installing an AC unit in the same window. Hopefully this will be of some use to other users.
I created a post on Thingiverse to share the 3D printed file and the SolidWorks model:
Thank you for mentioning this here. I did mention it in the Thingiverse post.
Some AC units have a vent feature, which could potentially pull in laser exhaust.
This particular AC unit does not have that feature, but it is something that should be considered if anyone else wants to use this idea.
