Official C12 Clone - Build and Support Thread

This is the official build and support thread for the C12 Clone project. All build related materials and pics will be posted first, and please feel free to post any technical, BOM, or assembly related questions. I'll update this if there are any changes or discoveries which are of a general interest to all builders.
