Summary

This is a stand for the Aqara Air Quality Monitor.
It's designed to make it possible to read the sensor's values from a wider range of angles. Besides that I think it looks prettier that way.

There are holes for the sensors on the sides and the button on the top as well as a bigger hole on the back which can be used to get the monitor out of the stand a bit easier.
The hole for the button on the top is pretty small which makes it a bit harder to press it. This is due to the size of the button in relation to the total depth of the sensor. I didn't want to make the hole bigger because that would mean that there would be almost no wall left around it on the front and back.          

Notes

Try scaling up the model in small increments of 1-2% if it doesn't fit inside your print.
