USB-A power insulator

thingiverse

This is a little piece to tuck into the usb type A plug to make it a data only cable. 5v will be insulated. Use case can be the connection between a printer and a host to ensure that the printer's controll board does not get powered by the host. Additionally it can make this plug-in more usefull for automattically connecting to your printer with octoprint: https://github.com/markwal/OctoPrint-PortLister I printed it as one single layer with 0.2mm.
