# Preparing the Tools Berkeley Humanoid Lite is designed for ease of build and ease of use. You only need a desktop-level 3D printer and a few common workshop tools to get started. ### 3D Printer You can print Berkeley Humanoid Lite on any desktop 3D printer with a build volume of at least 200 x 200 x 200 mm. We recommend the [Bambu Lab X1C Carbon](https://us.store.bambulab.com/products/x1-carbon) for its reliability and performance. Alternatively, the [Creality Ender-3 V3 SE](https://www.creality.com/products/creality-ender-3-v3-se) has also been successfully tested and used. ### Soldering Iron A soldering iron is required to connect the electronic components. We found the [SUGON A9 210](https://www.amazon.com/dp/B09QG887ZD) to be a reliable and affordable choice. Additionally, when installing heat inserts into your 3D-printed parts, a heat insert stand such as [this model](https://www.amazon.com/dp/B09SCRYWLR) is highly recommended to ensure a precise, vertical insertion. ### Heated Glue Gun A heat glue gun will be used to mount the magnet onto the motor shaft. Any standard heat glue gun will work, so you can use the one that is most convenient for you. ### Hex Tool Set The robot primarily uses M3 machine screws with hex heads as the fastener. A hex wrench set that includes sizes M2, M2.5, M3, M4, and M6 will meet most of your assembly needs. For certain electrical components, you will also require a Phillips (+) and a flat-head (-) screwdriver. Often, these screwdrivers are included with the purchased components listed in the next section. --- # 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.
