It measures 39.6 × 100 mm and has 2 copper layers, 1.6 mm thick.
72 parts, built around the 1N4148W and BC847. 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 marangisto/SteinerVCF repository on GitHub, at the commit this page was made from: the board is SteinerVCF.kicad_pcb. 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).
