'ABS printers' are starting to come with embedded filtration systems, and what looks like pretty well sealed chambers.
You certainly have put a lot of work into making your system work. I suppose it would be possible to balance having a "sealed" chamber using gaskets and enclosures while still having easy access for maintenance purposes.

How has has your system been working for you (I read your notes btw). Just curious on your thoughts.
