If you've survived building an LED cube before and would like to try your soldering iron on this project, I'm sharing the PCB file at OSH Park. This was my first custom PCB, so please excuse the giant mess. There is one mistake on it. The holes for the headers are too small, so I had to use remnant component leads instead of an actual header block. If you make one and willing to share, please post reply to this thread or on my YouTube video. It'll be awesome to see many tiny cubes!!!
