About this 3D model

It features a single continuous path for the batteries to travel through, eliminating possibility of clogging. Single part, no assembly and no support required. Just print with its back side on the bed. It is stackable and the intake can be accessed from both top and front so you can still feed batteries into it when it is stacked. The AAA version has the same external dimensions, can be stacked with the AA version or placed side by side.
