Home CNC breadboard power adapter

One really nice thing about having a CNC to make PCBs at home is the ability to whip up a quick adapter board in one night. Tonight I needed two adapters for a 5.5mm barrel jack, one to go to wires and one that can plug into a breadboard. Eagle allows you to make a board without a schematic which is exactly what I needed, just draw some traces on copper and route it out on the CNC. I used 40-60 mil traces and slapped on random switches I had laying around and an LED with resistor. The boards came out to be about 1.75″x0.4″ and routed perfectly with a 0.8mm router bit. I uploaded a zip with the Eagle board files and G-Code for anyone else who wants them.
