Custom 3D-printed PC trackball.

See the hardware directory for OpenSCAD design files.

The firmware directory contains the required Raspberry Pi Pico source code.

Further directions can be found in the READMEs in these directories.

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.
