Nice ! I'd love to see a video of this tool in action :)
This has nothing to do in the PCB contest !
That's a really great implementation ! No issue with water or condensation ?
Very cool idea and nice video!Please consider modifying the drilling steps (https://www.instructables.com/file/FUSKQ8DIPH0GHDO/ and step https://www.instructables.com/file/F1B193OIPH0GHQ7/) for safety reason: so many things ca go wrong when the part you are drilling is held by hand...
