The Reference Manual, every chapter, appendix, and build guide on this site, is published under the Creative Commons Attribution-NonCommercial 4.0 license (CC BY-NC 4.0). Plainly:

• You can read it, share it, and adapt it: print it for the bench, translate it, build on it.
• Give credit: attribute it to Jamey Warren / Makerphones with a link back here.
• Don’t sell it: no commercial use without permission. If you want to do something commercial with it, just ask.

Your builds are yours. Anything you make by following the manual, including things you sell, is not covered by this license; it only covers the written content itself.

Design files. The Daily Driver is genuinely open source, and unlike the manual, it carries no non-commercial restriction. The whole repo, CAD models, STLs, the headband DXF, and the design spec, is released under the MIT License. Download it, modify it, build it, and sell what you make. All I ask is credit to makerphones by Warren Labs.
