Making it yourself
PCB
"gerber" folder has the files needed for PCB orders, you can just send the ZIP file to the manufacturer of your choice.
Case & Plate
"KLE" folder has layout files that you can use to order plates and make KLE layout pictures for keymap readmes.
You can use the kle_raw.txt data to create plate files with ai03 plate generator or swillkb plate generator
There are a few different acrylic case designs in this repo

Questions
How big is the PRKL30 PCB?
It measures 254.9 × 62.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PRKL30 use?
94 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 PRKL30 KiCad files?
From the ErkHal/PRKL30 repository on GitHub, at the commit this page was made from: the board is PRKL30.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PRKL30 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).
