This is a pretty straight forward battery dispenser for AA batteries. It works sitting on a surface, but I also wanted the option to mount to the wall above my desk so I wasn't worried about knocking it over. It also helps to free up space having off the desk. Material was added to the back to make it a little thicker for the 3 holes for small tapered screws. You could probably get away mounting with only the top 2, but just in case I added the 3rd.

This prints with no supports needed.
