# Final Assembly

To test out your print you'll need to do some minor assembly. Start by trimming the PET to the printed outline. Be careful to not cut through any of the interior traces.

Next, Add some tape around the finger stylus to hold its shape.

Carefully pull down the black tabs on the connector of the companion board. This will allow you to insert your printed design.&#x20;

Next, plug your printed cable end into the connecter at the bottom companion board and gently close the two black connector tabs to lock it in place.

You're now ready to test the board out. The power button is in labeled in the center of the board. With the left potentiometer you can control the volume and with the right potentiometer you can control the pitch to tune the keyboard.

Finally, using the printed finger stylus you can play the keyboard by making contact with the keys.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.voltera.io/docs/nova/getting-started/starter-project/legacy-first-print-project-terra-nova/final-assembly.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
