Names and marks
The fab name and mark identify this project. Please don’t use them in a way that suggests we made or endorse something we didn’t.
Other products’ names and marks belong to their owners. They appear here only to show the tools fab works alongside, and that doesn’t mean fab is affiliated with or endorsed by them. A CC0 icon set frees the drawings, not the trademarks they depict.
