Hey all! Just got my glowforge in the mail- instead of grabbing the 1K solution or risking a non-vented first pass with the machine we came up with this! Under the photos I’ve added some links.
-# 4 in. Inline Vent Draft Blocker
-Poplar wood plank (we made sure the length was right for our window- you can ask people at home depot to trim it for you)
-all you have to do is cut a circular hole in the wood and then remove the plastic circular cover, but can put it back in when you dont use your machine.
Hope this helps!
