Gridfinity battery boxes, stackable

I created a set of Gridfinity battery boxes that are stackable. Included are the following boxes: 40x AA battery in a 2x3x56mm box49x AAA battery in a 2x2x56mm box16x AAAA battery in a 1x1x56mm box21x CR2032 battery in a 2x1x28mm box Even though the AA and AAA boxes are a bit higher than neccesary in order to stack them neatly. I used scheff`s gridfinity boxes as a base.
