Was not supper happy with the original square electronics bay, it was good for prototyping, but I need it to be more product looking. 

I loaded up Fusion and worked out this version. The PCB will be colored black and be visible under a 1mm plexiglass cover.  I have a schematic/PCB design going and when that is done I will send off for samples. The PCB will have all sensors and the JST connectors on it except for the outlet VOC sensor.  The new electronics bay is a much more pleasing shape and is smaller since I plan on going with a custom PCB. The bay is also higher on the unit and will help the inlet VOC sensor on the board be closer wit the inlet air. 

Also got around to making the fast swap filter that will be used for it. It is quite large and features a honeycomb prefilter/inlet and 1.5-2 cups loose activated carbon and then spiral of carbon mat, all wrapped in black paper.
