Customizable Battery Case: Common Sizes

I really liked the customizable battery case by walter: https://www.thingiverse.com/thing:57281 but you have to use thingiverse clunky customizer to generate the size you want.
This is a small modification that puts the lid next to the holder and a python script that generates a range of common sizes.

This remix includes battery holders for a range of common sizes and quantities including AA's, AAA's and quantities ranging from 2 to 50.
