I bought 2 chargers for my Garmin VivoActive 3 watch. They have a 36mm diameter disk with a metal back. None of the stands online have the cord coming from the bottom of disk with the charging point at the top/front of the disk. I added a inset for a 12x3 magnet and a tray to it because my watch has a silicon cover over the charging point that I don't want to lose.
