License

The firmware itself is licensed as GPLv3. It uses the Pi Pico SDK, licensed as BSD 3-clause, and therefore also TinyUSB, licensed under the MIT license. Some code is adapted from the TinyUSB examples. And the project uses the FatFS library, licensed as BSD 1-clause.

The hardware design is also licensed as GPLv3. It uses this Cherry MX switch model licensed as CC-BY-SA, and a Pi Pico case model licensed as CC-BY-NC-SA. But both are only used for visualization purposes and don't influence the 3D model at all.
