# Materials and Tools Before beginning a 3D-PAWS build, review the required materials and tools needed for assembling the station. Most structural components of the station are **3D printed**, but additional hardware, sensors, and tools are required for assembly and deployment. The **Materials and Tools spreadsheet** provides a complete list of the non-printed components needed to build and operate a 3D-PAWS station. The spreadsheet includes: * A complete **3D-PAWS parts list** * **Recommended tools** for assembling the station * **Sensor-specific parts lists** for the core instruments * Parts required for optional instruments such as: * Stream or storm surge gauges * Snow gauges Review this spreadsheet before beginning your build to ensure that all required components are available. → [**Open the Materials and Tools Spreadsheet**](https://docs.google.com/spreadsheets/d/10M0B0uvYnA0v-_q23aUk9Q1RNNS-oWH9inRZntQyyuM/edit?usp=sharing) --- # Agent Instructions: 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: ``` GET https://3dpaws.comet.ucar.edu/building-3d-paws/getting-started/materials-and-tools.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
