If you need to add a panel-mount connection for USB C, but don't have the time or tools to cut a custom oval or square hole, this USB C plug to USB Printer B socket Round Panel Mount Cable is the easiest and fastest way to panel-ify your project. It's about 30mm in diameter, so you can drill a hole in your wood, plastic or metal with a common hole saw or bit, no special shapes or filing are required. Unscrew the plastic nut, insert the plug and re-attach. Ta-da! Now you have a USB C plug to USB B socket adapter! This is good for when your device doesn't need more than USB 2.0 speeds and you want to use a flexible USB-C cable for the inner connection to connect to modern peripherals but expose a chunky USB B port. If you have a USB host device, check out this USB C to USB A host panel mount adapter. It's designed to easily attach to a panel up to 16mm thick (or 0.625"), or as thin as a few mm. Perfect for adding a USB B port to your project enclosure! We like this plugin, particularly for its solid body and 'forgiving' plastic lip that hides the drill hole.
