Desiccant Holder for Center of Spool

I couldn't find any other solutions for desiccant holders to go in the middle of the spool that I really liked, so I designed my own.

Because these screw into place inside of the center hole of the Spool, they will also get dried at the same time you dry your filament, so they can stay in there for the life of that spool.

I've uploaded two different widths depending on your needs. The 50 mm width x 60 mm height version fits Prusament spools perfectly.

For assembly, put your desiccant into the main body, then screw the "lid" into place to keep the desiccant secured when putting into place in the spool. Then you can put into the spool and screw in the "Cap".

There are two cap options, 1 to house round hygrometers like these https://amzn.to/4aGcrKI and one that is closed.
