Most commonly, plywood for laser cutting and 1/8" and 1/4" 6061 aluminum sheets are cheaper here than anywhere else. ### ePlastics Would you like some Delrin? Lexan? ePlastics is pretty cheap and easy to order from on-line. Would recommend. ### TECO Technologies If you need any **8020** extrusions or parts, this is the place to go. They give a 10% discount, but they sadly don't do sponsorships. They can also give some design advice and they can answer more specific questions about 8020 that can't be answered on the website (you can also search the catalog)! Michael and Benson have been in contact with David Morton from there. His email is Good customer service, highly recommend. ## Small Parts ### McMaster-Carr Screws, bolts, washers, nuts, threaded rods, tooling, some stock, and similar are the most common purchases from McMaster. Many other parts (gears, linear bearings, pumps, etc.) are available but may be prohibitively expensive. ### Swagelok If you need pipe fittings, valves, regulators, or really anything for propulsion, Swagelok is our go-to supplier. ## Electronics ### Digikey Buy components from Digikey. Really everything should come from here. ### Mouser If you can't find it on Digikey, maybe you can find it here? ### Arrow Apparently Arrow is actually the largest supplier of these three by volume, so you should probably be able to find it here if not at the other two. ## Machine Shop Suppliers {% file src="/files/-LdLp7NHXa6Qt9GICrq7" %} {% file src="/files/-LdLpGI1pCkuKMlDZZjX" %} {% file src="/files/-LdLpg\_lqxxnS4vLdp1\_" %} {% file src="/files/-LdLpjz3PjVfiYC29e52" %} {% file src="/files/-LdLpmkb-SSngHycAyLK" %} {% file src="/files/-LdLpr5G7q6pC8yR7w3\_" %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## 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://rocketry.gitbook.io/public/tutorials/manufacturing/suppliers.md?ask=&goal= ``` `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.
