The GCODE [here](/Users/antoniocarlosgoncalves/fabacademy2019/antonio-gomes/docs/assignments/FilesFolder/week14 Networking/CAMOutputs/networking1) and the board cutout [here](/Users/antoniocarlosgoncalves/fabacademy2019/antonio-gomes/docs/assignments/FilesFolder/week14 Networking/CAMOutputs/networking1_cutout)
All the files are [here](https://gitlab.fabcloud.org/academany/fabacademy/2019/labs/fct/students/antonio-gomes/tree/master/docs/assignments/FilesFolder) and at my personal google drive [here](https://drive.google.com/open?id=1Z9piwM9xCbg6XFwhQNHIXudWf7W6QhBY).
