Filament Spool Storage System

Keeping your filament dry is a great idea and with the exception of having dedicated electric storage vaults, vacuum bagging with reusable desiccant is the best solution. The web is full of desiccant storage containers you can place in a spool before vacuum bagging but they have one major problem. When you vacuum down the bag it seals off the desiccant so it cant reach the filament on the spool. We have come up with a solution following the same principal but created a top hat on the container that keeps that from happening. It provides air flow between the desiccant and the filament. It takes four things for this ultimate solution: Raccoon Engineering Desiccant Containers Reusable desiccant (Amazon Link) Reusable Vacuum Bags with pump (Amazon link) Hygrometer (Amazon Link) Note: Wash your build plate with dish soap and hot water really well for maximum adhesion of the spool top hats.
