The Eryone Snail Dry Box has a small compartment underneath for desiccant bags. Unfortunately the grid spacing that allows airflow is too wide to put your own desiccant.

This simple box allows you to put your own desiccant without all of it spilling into the components. It has a little cutout to make it easier to take out.

@Schumannity_907663 made a cap for this to avoid spilling which you can download here: https://www.printables.com/@Schumannity_907663
