This is a mounting bracket for the Harbor Breeze solar light converted to a Meshtastic node. This is intended to be screwed into something with wood screws. The mount uses the hardware that originally connected the solar panel to the light and has some detents to catch the ridges built into the solar case for a sturdy connection. I printed it upside down with no supports. The external LoRa antenna wire that came with the starter kit for the RAK Wisblock was just long enough to connect to the board when mounted to the (now) top hole of where the internal charge circuit used to be.
