The castellated module itself is OSHW, available here; OSO-BOOK-C2-01 is the filename, and if it’s like it was a year ago, I think that the zipped gerbers and the two CSV files should be enough for JLC to be able to run you a small run of them. https://github.com/joeycastillo/The-Open-Book/tree/main/Open%20Book%20Abridged/CAMOutputs
