Meet the Dock Box, a portable 3D-printed boom box inspired by rugged dockside gear. Designed around the versatile TW100U amplifier, the Dock Box can run on either a 12V or 24V battery setup and supports the amplifier's built-in Sync Mode, allowing you to link multiple Dock Boxes together for an even bigger sound experience.

Built with simplicity in mind, the Dock Box is an easy print with zero supports required, making it a great weekend build for makers of all experience levels. The enclosure is designed to accommodate most 6.5-inch speakers, giving builders flexibility to customize their setup.
