Slightly improved version (untested, not produced).
- Cleaned the folder structure. Now all the parts are in the same library, and all the 3D models are relatively referenced to the project path.
- Changed the transistor to a SOT23. Should be easier to solder.
- Increased the track width.
- Made the border slightly thinner, I think? I don't remember. Probably.
- Isolated the ground plane from the copper pour, because I suspect that it will improve the touch response, but I have no idea if it will work.
