This is a simple battery holder designed to make your drawers more organised. The battery holder can be used for AAA, AA and CR2032 batteries.
CR2032 batteries are held securely in place with clips. For rechargeable batteries, you may need to scale the models up by 3-5% (in the x and y axis).
Make sure your slicer doesn't print those thin walls between the batteries that you can see the holes in the first image. With PrusaSlicer, this works fine for me.
