3D model description

I present a compact portable wireless Bluetooth audio power amplifier dedicated to the Parkside X20V Team battery from the LIDL store.
The device is based on the inexpensive Wuzhi TPA3116 power amplifier module:
The module is equipped with a Bluetooth 5.0 audio receiver and jack 3.5 mm AUX line input.

You can connect to the amplifier external speakers or speaker sets with an impedance of 4-8 ohms.
The amplifier powered by fully charged 4Ah battery is capable of delivering the continuous RMS output power (1kHz, 1% THD) up to 2x20W/4R or 2x24W/8R.

WARNING! The switch built into the potentiometer does not disconnect the power supply from the device. Leaving the amplifier fastened on the battery will discharge the battery.
X20V batteries have no built-in over-discharge protection, so check the battery voltage and do not discharge below 15V.

This is my project of useful gadgets and portable wireless devices for Parkside X20V batteries. There are:
- Mounting brackets for the charger
- Battery mounting bracket (shelf and wall mount)
- Floodlight / Work Light - LED 10W
- Audio amplifier TPA3116 Wuzhi - maximum output power RMS 2x20W/4R, 2x24W/8R
- Power supply DPS3005 (max 19.5V/5.1A)
- Soldering station KSGER T12 OLED
STEP files are available so you can modify them to suit your needs.

You need:
- 1 piece Wuzhi TPA3116 power amplifier module
- 2 pieces long 6.3 mm connectors
- wires 0.75-1 mm2

The photos should explain everything.
Scratch the solder mask in the places shown in the photo. Coat the copper places with solder.
Cut the connectors as shown in the photos and solder the wires connections. Strip the ends of the wires.
Push the wires through the holes in the 3D print. Solder the ends of the wire and solder the connectors to the wires.
Put the connectors in place and secure them with CA glue.
Cut the wires to the correct length and strip ends. Solder the wires to the amplifier module.
Screw the amplifier module onto the 3D printed part.
