I know some have posted about their phones not charging unless positioned just right on the wireless charging pad. I had been using a small piece of foam to keep my iPhone in the right spot for continues charging. The other day I ran across a company that has two 3D printed option for aligning your phone on the charging pad. I ordered the Slim Phone Charger Adapter from pcbtechart.com. I used som 3M trim tape to keep it in place. Seems to work really well. Here is the link to the other version they offer (Phone Charger Adapter)
