Keytstone Blanking Plate

During Covid19 Lockdown I discovered mice were coming through a hole in the wall where my cables came in. I had some Keystone jacks and a wall plate with too many gangs, but no blanking plate.

This very simple and somewhat crude hack takes the USB Keystone Jack I found on Thingiverse - item 1349174 and blanks out the USB - making a passable blaning plate.
