This is a desktop stand that holds two RAK19007 Meshtastic radios that use TonyG's (https://www.printables.com/@TonyG) case design with a double 18650 battery configuration: https://www.printables.com/model/286657-rak19007rak5005-case-for-meshtastic
I like to use magnetic charging adapters on my radios, which causes them to not stand up straight. This desktop stand gives them a place to sit while also allowing a magnetic charging cable to connect from the bottom.
