It measures 41.4 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
18 parts, built around the BC548. 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 SON3DRA/PCB_varie repository on GitHub, at the commit this page was made from: the board is oscill_800Hz/oscill_800Hz.kicad_pcb and its schematic oscill_800Hz/oscill_800Hz.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask SON3DRA before reusing the design.
