I think that depends on how it was stored and if you have a way to dry it. I know some people will heat filament or use dessicant packs in an airtight container to restore old filament, but I’m not sure how effective those are since I haven’t tried any of them before.
Definitely would suggest getting new sealed filament for anything that requires tighter tolerances or parts that need to fit together though. The filament I had wasn’t breaking or making things look terrible, but it made the filament expand as the moisture boiled off in it, so the parts were all a tiny bit too big so no parts would fit together properly.
I think a discord server can be a useful tool, but a proper doc for things is also important. Definitely sucks when I want to look something up or troubleshoot an issue and have to search through discord threads for words vaguely related to my issue and find half a conversation spaced between year old memes and 3 entirely separate issues.
