About this 3D model

Desiccant holder for the center of filament spools. Tried a few of the ones already available, but kept having an issue where when removing the spool from the AMS the holder would slide out and drop on the floor. Decided to design my own from scratch that has won't fall out of the spool and also has a cap inside the container so once the outter cap holding it in the spool is removed, the desiccant is still contained.
