Moved the PCB edge to flush with the edge of the USB-C port, added the corresponding hole in the case, and added some text to the case. I also began the compiling process and ran into a whole bunch of errors and missed semicolons…
In the code that I am testing, all but one of the errors is fixed! I don’t understand the correct syntax for switching layers, and code in a different file is a ‘statement with no effect.’
