RAKwireless RAKBox-B6 - CO2 sensor extension

The new RAKBox-B6 is a nice indoor sensor enclosure for RAKwireless WisBlock based sensors. But it is not prepared for larger environment sensors, like the RAK12037 CO2 sensor. So I made a small extension to the existing mounting plate that helps to mount the RAK12037 CO2 sensor and connect it with the IO Extension Cable RAK19008  It is a fast 8 minutes print (PLA+, BambuLab P1S)   The extension requires no changes on the original enclosure. It is fixed through the existing mounting points of the mounting plate.   Mounting of the extension and the sensor is very simple. Arduino firmware (RUI3 based): RUI3-Sensor-Node-Air-Quality
