Exactly what the name says. It holds AA batteries and can be cut with a laser!
Mine holds 24 AA batteries. You could leave out the middle and upper guide if you want to increase the capacity.
I updated the DXF files for several problems. I added a boss for locating the roll stop when glueing. There wasn't enough space between the upper and middle guides for batteries to fall freely. The walls of the sides weren't low enough to easily remove batteries. Finally, I made the hanging holes slightly bigger to accommodate hardware I had on hand. I've included a .zip of the original DXF files just in case anybody wants it.
No pics of the updated holder yet, but I did find time to cut it. Assembles easily; all dimensions are correct; batteries are easy to remove at the bottom.
Slicey dicey some 1/8 (.125) inch material with a laser cutter. (mine was .123 and everything fit nicely)
Use an adhesive that's appropriate for the material to make everything permanent friends.
