Single Filament Storage Box
An open spool pulls moisture out of Indian air within hours — and wet filament is what strings, pops and snaps mid-print. This box seals a 1kg spool behind a gasketed snap-lock lid, stands it on a printed roller base so it turns freely, and feeds it out through a bulkhead port, so the spool never has to come out to print. Sold single, or in sets that cost less per box for a bench running more than one material.
- Fits 1kg spools to 200 × 70 mm
- Sealed below 20% RH
- PTFE feed-through fitted
Pick the symptom you recognize
Absorbed water flashes to steam at the nozzle, pulling thin trails between travel moves — retraction settings alone rarely fix it.
Dry the spool at 45–55°C for 4–6 hours, then store it sealed below 20% RH so it stays that way.
Seven days, one open spool of PETG
Dashed line: 60% RH, the point PLA and PETG begin absorbing moisture fast enough to affect a print within days. Sealed-container readings from the same shelf stay under 20% RH.
Keep the spool sealed, print through the seal
The Filament Storage Box holds a spool below 20% RH indefinitely, and feeds filament through a PTFE port — so it never needs to come out to print.

Enough to keep a single active spool sealed and feeding.
Run PLA and PETG dry side by side.
Best per-unit price — for four machines running different materials.
Yes, a food container plus desiccant can work
A gasket-sealed kitchen container and a bag of silica can hold a spool dry for roughly what a finished box costs. Here's exactly what you'd still need to source, build, and maintain — and where a finished product earns its price instead.

Stopped fighting brittle CF snaps the week this arrived. Prints straight through the port now.
The bearing feed is smoother than my old cardboard-box setup. No more stringing on humid days.
Does exactly what the spec sheet says. Wish the desiccant pack were a bit bigger for our farm.
