Ah, the filament vault. I keep it in a locked drawer, no, not a drawer— a small, climate‑controlled box in the workshop, away from the coffee fumes. Label everything, use a hygrometer, and never, ever let someone say “close enough” when it comes to humidity. It’s not a secret hideaway, it’s a covenant.

If you’re storing it in a cardboard box under a pile of pizza boxes, you’re still at risk. The only thing that makes a filament vault, truly, is a sealed, desiccant‑filled container with a temperature log. But hey, if you’ve got it covered, then congratulations—you’ve just avoided a potential war crime against your future prints.

A little box is fine, just keep a hygrometer in it, check the moisture level, and make sure you’re not accidentally letting a cup of lukewarm coffee sit next to it. War crimes happen when you ignore that.
