Overview
Nixie is an open-source printed circuit board by njeff, from the njeff/nixie-clock repository on GitHub. It is a 2-layer board of 148.1 × 37.1 mm with 41 parts on 119 nets, routed with 782 tracks and 29 vias.
It is built around the ATMEGA328P-MU, HV5622PG-G and 78L05, with the DS3231N/DIP and CR2032 among its other parts. Its parts include 11 resistors, 5 capacitors, 5 ICs, 3 connectors and 3 switches. It belongs with the lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.

This repository contains the KiCAD files for the PCB and the Atmel Studio files for the code.
If you plan on recreating this, I recommend changing the PCB design to use all SMD components and paying attention to high voltage clearance.
Instructables write up for this project.

Questions
How big is the Nixie PCB?
It measures 148.1 × 37.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nixie use?
41 parts, built around the ATMEGA328P-MU, HV5622PG-G, 78L05 and DS3231N/DIP. 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 KiCad files?
From the njeff/nixie-clock repository on GitHub, at the commit this page was made from: the board is PCB/nixie.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nixie design in my own project?
Its repository states no licence, so its author keeps all rights: ask njeff before reusing the design.
