Yet Another Battery Storage System

I know, I know, there are probably too many of these out there already, but the battery drawer was a mess, and we get our batteries at the warehouse club, so we end up with a bunch at a time, so I designed another one. They are stackable, so several configurations are possible. For the battery drawer, I printed one DcellCaddyx3, three AAcellCaddy, two AAAcellCaddy and one MiscCaddy. A smaller option would be one each of the DcellCaddy, AAcellCaddy and AAAcellCady for a single tower.
