The 13 most common of 17 parts.
It measures 57 × 47 mm and has 2 copper layers, 1.6 mm thick.
17 parts, built around the NJM2732D. 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 EduSpectro/EduSpectro4X repository on GitHub, at the commit this page was made from: the board is hardware/EduSpectro4X_07/EduSpectro4X_07.kicad_pcb and its schematic hardware/EduSpectro4X_07/EduSpectro4X_07.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).

This arm is not industrial and it will not be fast, but that is not my goal. But it will hopefully be a very nice looking arm fully capable of 6dof motion, cheap enough to keep it accessable but capable enough to…
