Summary
I needed a "step" for Nugget the cat would stop stepping on the the outlet adapter for my battery pack chargers and USB adapter plugs. I found the Smart Home Outlet Shelf and got the light bulb moment. I edited out the prongs for wrapping the cord because they got in the way of the adapter being plugged in. "Erasing" the prongs made the perfect "step" for the Nugget to get in and out of the window without pushing the plug adapter out. You can see in the picture it works puurrfecty.

Printed on its back (the outlet side) with supports.
