This is a (by far) the simplest AA storage box designed for rapid printing.
it fits 36 AA batteries with ease of access.

It's designed for rapid printing (0.6 nozzle) with appropriate wall thickness to match 2 perimeters with the following assumptions:

; external perimeters extrusion width = 0.80mm
; perimeters extrusion width = 0.80mm
; infill extrusion width = 0.80mm
; solid infill extrusion width = 0.80mm
; top infill extrusion width = 0.65mm
; first layer extrusion width = 0.80mm
