This battery holder is designed for quick and easy 3D printing while keeping a cute and practical design. The lid uses a clip system to stay securely closed, letting you mount the holder in any position – even upside down! It also includes two side covers to hide connectors, with multiple holes for cable exits. This set includes files for a 4xAA battery holder, and I've also provided STL files for 2xAA and 3xAA holders.
