AA & AAA Battery Dispenser Remixed

Remix of https://www.thingiverse.com/thing:3358129

I changed it so the back is a full face and aligned the vertices at the bottom so the entire bottom would be flat on the build plate. The original model's bottom wasn't perfectly flat so the front would touch the build plate before the back of the model and would cause issues.

I also made it a little smaller in depth so it would fit on the build plate for an Elegoo Mars 2 Pro.
