This thing holds a round wireless cell phone charging pad and the phone above it so that the phone is perfectly centered on the pad (and stays that way despite kids, pets, etc.)
About a month ago I ordered one of the round wireless charging pads that are common on the Internet. It works great as long as the phone is placed perfectly centered on the pad. If it is a little bit off (or the table gets bumped) it will not charge the phone. I had gotten fairly good at placing the phone on the pad but I knew that I could use my 3D printer to make it easier.
This thing is customizable for any phone and round charging pad.
