Simple battery storage with 9V

This is a remix from https://www.thingiverse.com/thing:3673388
I just added three 9V compartments.
There are some minor glitches but it remains overall functional.
I have also resized by 2% as Akanar said in his commentary. This is because all battery are not the same size.

15 x CR20xx
12 x AA
16 x AAA
3 x 9V
140mm x 88mm
