Redesign of the Plaid PCB to use USBC and 2u stabilized layouts
Assembly and BOM generally follows the standard Plaid with the exception of the USBC port (USB4085-GF-A GCT) and 2 additional 5.1k resistors for C to C identification. The PCB can also now take PCB-mount 2u stabilizers for the 2u spacebar locations, clip in or screw in will work.

Questions
How big is the Plaid PCB?
It measures 228 × 98 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Plaid use?
142 parts, built around the ATMEGA328-PU. 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 Plaid KiCad files?
From the worldspawn00/PlaidC repository on GitHub, at the commit this page was made from: the board is plaid.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Plaid design in my own project?
Its repository states no licence, so its author keeps all rights: ask worldspawn00 before reusing the design.
