In addition to making handcrafted pens I sell maintenance, parts and operator manuals for interstate and transit buses that were manufactured from the 1920s to the 1980s. About 20 years ago I scanned all of the hard copies to PDF files and burnt them to CDs. It seems now that fewer and fewer people have CD drives but they do have USB ports.
It’s easy to put a label on a CD but where do you put a label on a thumb drive?
Glowforge to the rescue.
