29 parts, built around the ATF22V10C-7PX and 74HCT163D. 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.
From the ngdrascal/12BitCounter repository on GitHub, at the commit this page was made from: the board is src/EDA/Circuits/Counter12Bits.kicad_pcb and its schematic src/EDA/Circuits/Counter12Bits.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
