About this 3D model
This is a typical power tool battery holder with provisions to make a rack. The battery holder can simply be screwed to a surface, or with some added work be combined with the side rack pieces. Will be adding a tool holder as well, but for now a heat set 4-40 insert can be inserted in the side holes with a soldering iron, then you can screw the side pieces to the battery holder. Allowing you to condense your battery storage.
