Feet of microwave enlightenment

I wanted to put my microwave on top of the fridge to save space, but the door hinge and some other junk up top prevented me from doing so. Until now.
Behold: feet to raise your microwave to new heights.

Height above surface is 17mm, which is the height of my door's hinge hardware above the fridge "roof." The foot extension has a slight indentation to hold the microwave's built-in feet.
