Your best bet would be to put it into a oven at about 6o to 70C for 8 hrs. Then you could use the box to keep it dry when you are printing that works for me. **Q: How do you work out humidity?** A: With pla it will be brittle and snap easily if it’s dry it will just bend **Q: Can anyone tell me the maximum width of a spool that this can hold? Or if a Prusament spool will fit inside?** A: The max size is the width of a 1kg spool, atleast thests the biggest I've put into it and that's quite snug ## Frequently Bought Together - SUNLU Official Filament Dryer S1 Plus, Built-in Circulation Fan, Filament Dryer Box Storage Box for 3D Printer Filament 1.75 2.85 3.00, S1 Plus White - SUNLU PLA 3D Printer Filament PLA Filament 1.75mm, Neatly Wound 3D Printing Filament, Dimensional Accuracy +/- 0.02 mm, Fit Most FDM 3D Printer, 1kg Spool (2.2lbs), Good for Lithophane, White - Dry & Dry [2 LBS] Blue Indicating Silica Gel Beads Desiccants (Industry Standard 3-5 mm) - Reusable Desiccant Beads Silica Beads(Blue to Pink) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/712222798-sunlu-filament-dryer-s1-plus-3d-filament-dryer-box-pla](https://www.desertcart.jp/products/712222798-sunlu-filament-dryer-s1-plus-3d-filament-dryer-box-pla) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-17*
