A simple Multibin insert for holding three RAK Wisblock 19007 boards when doing firmware updates, etc. The three boards are stacked height-wise so that the battery and solar panel connectors are not obscured by the board in front, and the separation is sufficient for the boards to be configured in the Meshtastic Starter Kit version, without making contact with each other. The holder is designed to fit tightly into a 1x1x1 - Bin - Multibin Insert and to hold the boards securely.
