My coworker often welds in conditions that are hazardous. He asked me to make him an adapter for turning a scuba mask he had that would allow him to put a welding lens on it. So, I took the one that was in his old welding helmet, and recreated its enclosure, but shaped to the curve of the scuba mask. I figured I would put this project here, and upload the files to help anyone who may need a similar device. Feel free to message me if you need help creating your own.
