# 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.
