This is a compact 3D-printed enclosure designed to house the internal power supply and audio components for a DIY Bluetooth device — such as a portable speaker.
The case integrates a Li‑ion battery with a TP4056 charging module, an MT3608 step‑up boost converter (3.7V → 5V), a Bluetooth module, and a 3‑section 3.5mm audio jack for headphones or audio output.
A SS12F15 toggle switch lets you easily switch between two modes:
- Operation mode — device runs on battery power
- Charging mode — battery charges via microUSB (without powering the load)
