With the layout decided, I could move on to making both the PCB and the plate. I have little experience here, but thankfully there's really good guides and tools to help out anybody who's willing to sit down and go through all the information and documentation.
The plate came first from lasergist, and they did a fantastic job on it too. Everything is to spec and the stainless is a nice quality with a good finish. I'll have to brush up on my own CAD skills or dive deeper in to how the plate maker works so I can make my plates have multiple layouts and options.
Next, the PCB it's self. This one was nicely easy to lay out because of the spacing between the keyswitches. I also had a bit of help from people in the community helping me learn best practices and what makes a good board and a bad board. I used Eagle CAD for this, mostly because I've done a few projects with it before, and I'm used to the ecosystem as well. If this build interests anybody, I can share the gerbers once I know I have a working board.
Oh... Uh, shoot. I guess this is why they say triple check, and then check again before submitting anything to fabrication. It turns out I had one of the data lines incorrectly routed on this board. I guess I'll have to fix things and then wait for my new set of boards.
