I left this project because it is very expensive. For me these were the numbers: - PCB for JLCPCB would have cost around 52 USD - Plus all the components (not including the keys) around 170 USD - The keys are not that…

Questions
How big is the Uniform Stagger 40 PCB?
It measures 282.2 × 86.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Uniform Stagger 40 use?
181 parts, built around the ATMEGA32U4-AU and SK6812MINI-E. 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 Uniform Stagger 40 KiCad files?
From the LeafKeys/Uniform-Stagger-40-Project repository on GitHub, at the commit this page was made from: the board is Uniform Stagger 40/Uniform Stagger 40.kicad_pcb and its schematic Uniform Stagger 40/LEDs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Uniform Stagger 40 design in my own project?
Its repository states no licence, so its author keeps all rights: ask LeafKeys before reusing the design.
