Generic customizable battery spacer - OpenSCAD

Battery spacer to create your own battery pack. You can modify battery size, grid size, wall and bottom thickness, spacer height, and the size of the connection strips.
I created this with my son as most spacers found here have a gap between the cells and that is taking space we needed. Also the bottom has cut out circles to keep as much rigidity as possible.

Feel free to use the code and update it to your own needs.
