Just a simple battery holder. I bought two 5-pack batteries and used one so that leaves 9 batteries I need to hold. These hold the A23/23A 12V batteries you find in some house hold remotes. I added a top with no text in case you want to add your own text in the slicer software.
The author remixed this model.
I cut the model, mirrored it, shortened it to remove sharp edges, and replaced the text to add another row of batteries.
