I have too much stuff for one lol. I use one of the hobby/tackle organizers for backup storage - screens, little glass pieces, replacement parts, mouthpieces, filters, adapters, cleaning parts, old grinders that I don't use anymore. Pretty much anything vaporizer related that I don't use daily gets held here.
I use a tray for everything currently in use - screens, silicone adapters, battery cases, grinders. And on the tray I use an old 1/8th glass jar from a dispo to hold brushes and other random things q-tips, dab tools, pokers.
