USB-A power insulator
thingiverse
This is a handy adapter that fits snugly into the USB Type A port, transforming it into a data-only cable. The 5V power supply is cleverly insulated. Its primary function is to serve as a connection between a printer and its host, ensuring the printer's control board remains powered off while still allowing for seamless communication. This safeguard prevents accidental energizing of the printer's control system by the host. This adapter also makes it incredibly convenient to automatically connect your printer with OctoPrint via the PortLister plugin on GitHub: https://github.com/markwal/OctoPrint-PortLister The design is simple and efficient, requiring only a single layer print at 0.2mm resolution for optimal results.
