Questions
How big is the Eg48 PCB?
It measures 245.1 × 73.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eg48 use?
110 parts, built around the MMSD4148 and WS2812B. 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.
Where can I download the Eg48 KiCad files?
From the and3rson/eg48 repository on GitHub, at the commit this page was made from: the board is kicad/eg48.kicad_pcb and its schematic kicad/eg48.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eg48 design in my own project?
Its repository states no licence, so its author keeps all rights: ask and3rson before reusing the design.

I wanted to make a case for the Serdaco DreamBlaster X16. Since I rarely do anything half-way when it comes to visualization, I busted out the datasheets and got to work. This is not a functionally accurate PCB.
