My personal nixie-tube clock made from 4 Mullard ZM1175 Nixie-Tubes.
The project includes schematic, PCB and a footprint I made for the ZM1175 Nixie-Tube, including an approximate 3D model of the tube.

Questions
How big is the ZM1175 PCB PCB?
It measures 30.3 × 42 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ZM1175 PCB use?
10 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 ZM1175 PCB KiCad files?
From the SimsesLab/ZM1175-Nixie-clock repository on GitHub, at the commit this page was made from: the board is ZM1175_PCB/ZM1175_PCB.kicad_pcb and its schematic ZM1175_PCB/ZM1175_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ZM1175 PCB 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).
