Outlet guard

I got tired of my son pulling out the power cord for his baby monitor and camera in the nursery, so a friend and I came up with this. The two holes at the bottom are for strain relief; wrap the cords around them once or twice like a boat cleat to prevent any tugs from straining the connectors. I've included the test print, which is just the center post, which I used to check settings and clearance on the outlet. I was able to use the same screw from the wallplate to mount it.
