If you have holes in your cabinets where things like the microwave plug had to go through (trailing the cord behind) this is the fix. Not glamorous, but something my wife could see and appreciate as I continue to try to explain what the 3D printer is for.

The specifics of an item like this vary from use to use. The model is at Tinkercad.com where you can edit it to your needs. Otherwise, download the STL and use your slicer to scale it to suit your purposes.
