Questions
How big is the Nixie-2.1 PCB?
It measures 167.1 × 142.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nixie-2.1 use?
89 parts, built around the MPSA92, MPSA42 and MUR160GP-AP. 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 Nixie-2.1 KiCad files?
From the jhrg/nixie-2 repository on GitHub, at the commit this page was made from: the board is PCB/nixie-2.1/nixie-2.1.kicad_pcb and its schematic PCB/Z573M-display/Z573M-display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nixie-2.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jhrg before reusing the design.
