This is a compact and creatively designed 3D-printed mini battery holder inspired by the shape of a classic beer crate. Made from smooth, light-colored filament, it features a sturdy rectangular structure with multiple compartments to neatly organize different types of batteries. The top section includes vertical slots perfectly sized for cylindrical batteries like AA or AAA, while the lower compartments are designed to hold button cells securely in place. Its grid-like layout keeps batteries separated and easy to access, preventing clutter and improving organization. Both functional and visually playful, this miniature “beer crate” battery holder is a practical and stylish addition to any workspace or electronics setup.
