So, the idea of a travel case is to make it easier to pack and use when traveling. This really is just a box to keep it in. Could easily add in separate, divided areas for tanks, main unit and nose pieces. Then everything could dry like it’s supposed to. Remember, if you’re using it in the morning before checking out, you have zero time for this to dry. Then it’s stuck in a suitcase until you arrive at your next destination. That means 10-12 hours of moisture and then it’s time or almost time to use it again.
