I used Autodesk Eagle to create a scheme. I found a label tool pretty useful.

Now I got a connections that I have to sort out.

I tried to make the board in one dimension, but I soon realized that it is inevitable to use the both side of the board. Refering to the tutorial I decided to make a 2-sided board, with a proper size of the rivet holes. This is the final result of the design.

I exported the trace into dxf, and imported it to the Illustrator, then export to PNG file.

Now to milling!
