It measures 351.8 × 100.3 mm and has 4 copper layers, 1.6 mm thick.
186 parts, built around the CAHCT1G125QDCKRQ1 and ISO1050DUB. 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.
From the Deltaphish/stensgrind repository on GitHub, at the commit this page was made from: the board is stensgrind_pcb/stensgrind_pcb.kicad_pcb and its schematic stensgrind_pcb/left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
