Large “Costco Size” AA/AAA/9V Battery Tray

This battery tray is made to hold 40 AA batteries, 40 AAA batteries, and eight 9 volt batteries. These are the amounts you will get if you purchase a pack of Duracell batteries from Costco in each of the three types. It will of course fit any brand of batteries you have. I printed it in PLA with no supports or brim.
