Filament Dry Box (Cereal Container with Indents)

Insert to convert the Utopia Cereal Containers into a filament dry box.

(with indentations, tested with 4-pack and 3-pack models) 

Also, see my other version with rollers: Filament Dry Box with Rollers

See my other model for Filament Labels

Desiccant box prints separately and snaps into place (so it can be swapped out or dried separately).

Updates

2025-01-26

• updated the base to accept a modular hygrometer holder

v2.0

• Full redesign using base plate from my design with rollers (Filament Dry Box with Rollers)
• supports wider spools, but the container limits overall width
• wider spool holders with inward chamfer to keep spool centered and prevent falling off
• reduced total filament usage by 13% (36.34g → 31.59g)
• Desiccant box is about the same volume as before
• Now fits both 4-pack and 3-pack designs

v1.0

• original version
• NOTE: this was designed for a 66mm (bambu labs) spool. If your spool is narrower it might not fit properly
• only works with utopia 4-pack design (3-pack doesn't fit)
