Off the subject, but that's some really nice work. Also, the dark/light mode toggle is much appreciated!

Your first page talked about how a glued seal doesn't work because "plastics aren't vacuum-tight. Molecules of gas can squeeze inbetween the polymer chains and slowly seep in." Seems like there are a lot of different glues and epoxies you could try. Are they all that bad? Specifically, have you tried UV-cure glue?
