If you need to add a compact panel-mount connection but don’t have the time or ability to cut a custom oval or square hole, this USB Micro-B Small Round Panel Mount Extension Cable is the easiest and fastest way to panel-ify your project. The adapter can fit holes 12mm to 18mm, so you can drill 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 micro B jack and plug for connecting any cable.

It’s designed to easily attach to a panel up to 13mm thick (or 0.5″), or as thin as a few mm. Perfect for adding a USB micro B port to your project enclosure! We like this plugin, particularly for its solid body, small aperture, and ‘forgiving’ plastic lip that hides the drill hole. It also comes with a cute protective cap that can be used to protect the port or cut off with scissors if you prefer.
