Micro USB Voltage Isolator

This is a simple case to hold a micro USB breakout board and a male micro USB plug for purposes of isolating the motherboard in a USB printer from the USB supplied 5v power. The CR6 motherboards appear to have an issue with the printer motherboard trying to draw too much power from the USB connected to your computer or octopi when the printer is powered down, leading to burned USB ports and electronics. I understand other printer motherboards may suffer from the same issue, but the ones that I know of are the CR6 boards.

There's a couple of solutions available, including taping the 5v pin on the supply side, hacking a usb cable to cut the voltage line, and a couple of commercially available power isolation devices. I had the board and plug sitting around in my miscellaneous projects part, so I drew up a quick case, printed it and soldered it. I'm sharing it here in case it might be helpful to someone else.
