Bluetooth TWS speakers

Portable TWS stereo speakers. Can be used separately.
The middle part can be printed of semitransparent plastic to make the status and charging LEDs visible.
The lipo charger module better to fix with a superglue, **not** hot glue, because it can melt during charging.
If the speakers are resonating during play you can fill the inner space with some soft material (e.g. cotton wool).
Assembling hints on photos.
