How to view the Gerber File?

Many of the email I got is about how to view / edit the PCB. In fact, you can easily view the PCB  Gerber with online gerber viewers. 

By uploading the Gerber file on NextPCB Gerber viewer, you'll able to see all the errors in order to make sure your design is ready for manufacturing. Feel free to try that out!

If you want to edit the PCB, the source file are also included in the repo where you can open with another online editor. So don't hestiate to try out and make yourself a special edition of the switch ! (e.g. add a type C port)
