HSV, first of all hello and welcome to the forum. I see this is your first post. We look forward to your participation.

The enclosure looks good. Did you build it because you were having issues with prints or did you just want a vent for fumes, or both. If you built it to help solve print problems with lift and warp can you tell us a bit about your decision to build it. And finally, please do report back and let us know how well it solved the problems you built it to solve. As you know, it's all about "solutions." I'd personally like to track how well your design solves problems.
