Modular Dry Box Filament Rack with Hygrometer

Modular dehumidifier rack designed for use inside sealed storage boxes for 3D‑printing filaments. The structure is 3D‑printed in PETG, providing good mechanical strength, thermal stability, and increased durability in humid environments. Each module is sized to support one filament spool and can be chained together, allowing the user to build a system with as many modules as needed, depending on the number of spools and the size of the container. The body includes internal cavities t
