I have an Ender 3 and I am going to print both housings also (AQMII+RX).
But it will take a bit of time . --> Then I will upload the makes!

Hello,

I have Ender 3 about a half of year, but I have to say the 3D printing is nothing easy...
So far I have been printing mainly some add-ons for my own printer and a couple of babies for kids.
For larger print, I have not yet dared and did not have enough time. For "meteo" I printed
only one thing:



(It prepared for solar sensor to Austria.)

... and this is my new case for mobile indoor AQM, but it isn't done yet:

 

Some other "enhancements" occurred during the construction:  
1) LED ???
a) green LED for CO2 <1500 ppm
b) orange for CO2 1500-3000 ppm
c) red flashing LED for CO2> 3000 ppm
maybe some buzzer?
2) CO
connect another sensor for CO ???

Hi Zdenek,

I have the same feeling, that's why I'm looking for user opinions.
In the meanwhile, my order from 3D HUBS was lost somewhere by the delivery company (strange as it happened with DHL). 3D HUBS customer support has been fantastic on all this process, and they are now doing a reprint which will be sent to me ASAP by priority mail.

1) - I'm afraid there isn't any free pins to connect the Leds
2) - A second CO sensor or another type?

ad 1) Yes, it is clear, but - it would be nice into school classrooms...
ad 2) Not just CO2, but also CO sensor - I know, we haven't now how to connect it, but it would be nice into a room with gas appliances...
But these are just ideas that might be good. 

Good night!

Finally done...

Don't take that to the airport

Hello Zdeneck,

Looks like it will have the capability to attract the students attention at school, which I think is one of the purposes of this build.
It will be easy to explain the role of each sensor.

I would like to have the skills to write a little program in pyton (or any other suitable language) to use the IoT capability of the AQM II, where the students, on their computer could define a threshold for the CO2 or PM2.5 readings, and then get a warning message or even play a buzzer (Ideas for the IT class).

Thanks for sharing with us this different assembling for a different purpose.

I would like to see a picture of any of those boxes printed by one of our users who have 3D printers. I think would be interesting sharing experiences about how easy or hard is for a beginner 3D print the boxes.

Is it possible that no one had tried?

I printed one last week on my Prusa i3 in Grey PLA, very easy to print if you are used to operating a 3D printer..
It came out very well at a layer height of 0.2mm.
I didn't notice when I downloaded the design that this box won't accommodate the SDS011 particle sensor sadly though.
