It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
24 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.
From the D4p0up/ValveLord repository on GitHub, at the commit this page was made from: the board is ValveLord.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask D4p0up before reusing the design.
