----- Object information -----
Battery storage tray (w/o electric contacts) for A / AA / AAA round cells. Fully customizable regarding cell type and number of cells + some further geometric parameters.

A slot for a rubber band can be created to keep the cells isolated and in place during transport. I have these in my R/C tool bag to carry spare
