This is a remake of my original as some spools were making contact with the original model.
I didn't like the easy way to spill desiccant in the original model(s) of the drybox. I simply made a container that fits perfectly in dryboxes that can easily be snapped close to avoid spills. These work great for other containers, as well, due to their low clearance and relative small size. I now use them inside my general filament storage containers.
