The 49 most common of 53 parts.
It measures 190.5 × 32 mm and has 2 copper layers, 1.6 mm thick.
53 parts, built around the HV5122PG-G and IN-12B. 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 wrickert/NixieClock repository on GitHub, at the commit this page was made from: the board is NixieDriver_KicadFiles/Nixie.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask wrickert before reusing the design.
