Questions

How big is the GBaller PCB?

It measures 12.4 × 13 mm and has 2 copper layers, 1.6 mm thick.

What parts does the GBaller use?

20 parts, built around the SM351LT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the GBaller KiCad files?

From the germ/gergo-trackball repository on GitHub, at the commit this page was made from: the board is gBaller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the GBaller design in my own project?

Its repository states no licence, so its author keeps all rights: ask germ before reusing the design.
