I have build up some stuff on breadboards by now, but often I have trouble with double row pin headers. So I decided to make an adapter as my first PCB design. Simple thing, a double row pin header on one side (female for direct access or male for ribbon cable), and two on the other side, far enough apart to fit across the middle gap of a common breadboard.

As I have to solder on both sides, I need it to be plated-through, so i’ll have to have it manufactured. Seeedstudio seems to be a very cheap possibility for a small batch.
I attached my KiCAD project. As this is my first try, could anyone have a look and tell me if this will result in what I want? The 3D image from KiCAD looks right, but I can’t make out the drilling holes in the board layout, for example.
