Even though the Gecko Node does not have to be water proof, it will be used outside. Because of this the PCB needs some kind of protection. I decided to make a simple 3d printed case in Fusion360.

This is what I came up with. It's the smallest shape to include the pcb with its battery holder. The lid is press-fit to the shell so there are no screws needed. A small hole above the HDC1080 ensures accurate humidity readings.
