A month ago I was storing spools in small sealed boxes with desiccant. Worked okay, but I kept forgetting which spool was where, and the humidity in each box was inconsistent.
Then I picked up a big cabinet that holds all my spools in one place, with a built-in dehumidification system. It sits at a steady ~25% RH now.
After a month:
- Stringing basically stopped
- No more popping/crackling during prints
- My PETG actually feels dry now instead of brittle
- Easy to find spools — everything’s in one place
Not a plug — just wanted to share what worked for me. If you’re in a humid climate and dealing with moisture issues, active dehumidification storage is worth looking at.
