BentoBox HEPA Top Cover and Carbon Bottom Cover

Covers to shield the bottom of the Carbon box and top of the HEPA box when BentoBox is not in use. See pictures. The reason for these covers is that I pull the Carbon/ HEPA units out (together) when the BentoBox isn't in use, and seal it in an airtight container w/ desiccant, hopefully to extend the life of the filter and carbon. These covers just make that more convenient. These use the same 4x2 magnets that the original pieces do.
