This item was created to prevent our foster kittens from pulling out the electrical plug. We regularly foster mother cats, and their litter will begin to play with anything, including the TV's power cable. This prevents them from either un-powering the TV off or getting zapped.

Quick and simple. The arch will straddle over a 27mm tall plug.
The Fusion 360 files are included for others to change the parameters to fit other plugs.
