Big cabinet vs small dry boxes vs just the AMS — what's your setup?

Bambu Filament and Accesories

After weeks of chasing “mystery” print failures (stringing, zits, brittle parts), I finally figured out my filament was absorbing moisture sitting out in my ~65% RH room. Embarrassing how long that took. :sweat_smile:

Now I’m trying to settle on a long-term storage setup and I keep going back and forth:

  1. One big sealed cabinet (180L-ish) — set and forget, but it eats floor space
  2. A few small sealed dry boxes — flexible, but you end up juggling spools
  3. Just drying in the AMS right before printing — works great, but everything sits exposed the rest of the time

Right now I run a mix: sealed box + molecular sieve holding around <20% RH for the spools I use most, and the rest… ziplock bags. :smiling_face_with_tear:

Curious what actually holds humidity well long-term vs what just looks good on paper. Does anyone run a hygrometer inside their cabinet — what RH do you actually see? And for the big-cabinet folks: is it storage-only, or do you dry in it too?

I usually just store then in zip-lock bags but I don’t have loads of spools.

How many spools are you taking about?

How does the sealed cabinet work? If you go to get a spool from it then does the whole thing become unsealed? Doesn’t sound good to me, if that is the case.
