Print the Enclosure, Right Connector, Left Connector (flip the model for right connector along Y axis), Washer, and D-ring (optional. there is one also included in your kit). We recommend using regular PLA. Other materials such as matte PLA can be too brittle for the parts to work properly.

Connect the battery to the PCB.

Connect the wiring harness to the PCB, being careful not do damage it. Look a the R+/R- and L+/L- labels on the PCB to find each lead.

Push the pogo pins from the wiring harness into the right and left connectors. The hole towards the flat side of the connector is the positive lead. It helps to use a soldering iron set to a low temperature (100°C works well) to help the pin slide into place. You want just the tip of the pogo pin to stick out of the other side, not the body.

Snaps the PCB onto the pegs inside of the enclosure. Make sure to have the USB-C port lined up with the hole in the side. Before snapping it in, make sure the gap in the peg is clear of any material so it cal flex properly.

Put the battery into the enclosure like pictured.
