It is a custom keycool84 size keyboard with dual oled screens and a rotary encoder.
I made this project to improve my cad skills and pcb designing skills. Also, i need a good keyboard to write my homework with.

Questions
How big is the SnakeBoard PCB?
It measures 315 × 152.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SnakeBoard use?
193 parts, built around the 74HC165D and SK6812MINI-E. 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 SnakeBoard KiCad files?
From the Nadoooor/SnakeBoard repository on GitHub, at the commit this page was made from: the board is PCB/SnakeBoard.kicad_pcb and its schematic PCB/SnakeBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SnakeBoard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
