The 128 most common of 132 parts.
It measures 152.4 × 96.5 mm and has 4 copper layers, 1.6 mm thick.
132 parts, built around the ATMEGA2560V-8AU, TSR 2-2450, STP55NF06L and BSS138. 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 gdck/fdmbox_pcb_tiny repository on GitHub, at the commit this page was made from: the board is fdmbox_pcb_tiny.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
