As of right now this is revision 4. I know it could be improved very, very slightly by changing the position of key groups by less than a millimetre but I think it's complete now.

Questions
What parts does the Left use?
101 parts. 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 Left KiCad files?
From the nikital/keyboard repository on GitHub, at the commit this page was made from: the board is pcb/left/left.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Left design in my own project?
Its repository states no licence, so its author keeps all rights: ask nikital before reusing the design.
