I really liked ottaross's AA battery dispenser so I modified it to have two holes for drywall screws and scaled it to fit standard US battery types. I added the wording "charged" to the front as I use it with rechargables. Pretty easily removed with a quick drop into Tinkercad and a "hole" box if you don't like it. I also altered the center channel to permit printing it without supports more easily.
Though these have holes for wall mounting, they also stand upright on their own.
