Desktop Battery Storage

I got tired of misplacing my batteries and mixing dead batteries with new ones, so I designed this simple battery holder. I may come back to this model and try to shave off some filament and improve the design in the future, but for now it does its job. It holds 16 AA and somewhere around 20 AAA batteries.

Am open to any feedback or suggestions, so please upload your makes and any comments you may have!
