Overview
Skrhade singlepcb is an open-source printed circuit board by jonboh, from the jonboh/skrhade_singlepcb repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 16.5 × 18.5 mm with 12 parts on 13 nets, routed with 37 tracks and 0 vias.
It is built around the SKRHADE010. Its parts include 5 resistors, 5 diodes and 1 switch.

These PCBs were designed to iterate on a dactyl design mounting these switches.
These switches can be acquired in Mouser and probably other electronic component stores.
The file skrhade_fabrication.zip can be used to order a set of these. Note however that design i not very good, in the effort of making the footprint as small as possible I did not realize that the wiring would be much easier if there were pads for each point (R1, R2, R3, R4, R5, CN) on both sides. Otherwise you need a common point for all switches. I fixed this by soldering all wires to a central point and using hot glue as insulator.
I did not continue with the Skyl project, otherwise I would have made the change in the design and ordered a new set.
If you want to continue with the design, I would advise adding a bit more vertical space to the PCB and adding the missing pads of both sides, wiring will be much easier, and similar to the single pcbs used in keyboard desings with typical switches.
This project was inspired by the harite, I used its footprints for the single PCB.

Questions
How big is the Skrhade singlepcb PCB?
It measures 16.5 × 18.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Skrhade singlepcb use?
12 parts, built around the SKRHADE010. 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 Skrhade singlepcb KiCad files?
From the jonboh/skrhade_singlepcb repository on GitHub, at the commit this page was made from: the board is skrhade_single_pcb.kicad_pcb and its schematic skrhade_single_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Skrhade singlepcb design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
