Spool Desiccant Holder - Hollow Core (AMS Compatible)

The Spool Desiccant Holder (SDH) is engineered to fit into the center of a filament spool, keeping the filament dry with reusable silica-gel or drying packs during storage. The SDH Body is inserted into the spool's core, and the threaded SDH Cap screws on securely, ensuring the holder stays in place.

Designed with finger tabs, the SDH is easy to secure and remove. Its conical ends and newly added hollow core are crafted to maximize the internal surface area, enhancing the distribution of silica-gel beads. The SDH requires no additional supports, assembly, or tools for installation and removal—just the cap and body. 

For easy filling, be sure to grab the specially designed funnel for use with the hollow core: https://www.printables.com/model/981945-sdh-hollow-core-funnel

A hollow tube is added to the center of the container to increase the surface area available to the desiccant.
