Mini hygrometer housing and mounting solution

I designed a compact housing for these inexpensive round mini hygrometer/thermometer units.

The housing has clearance for a 3mm screw, and vents in the back to allow for air to pass through to the inside for measurement. 

I designed this to work with my ball mount here:

Print using a material appropriate for the environment where you will use the hygrometer.  To assemble, use a 3mm screw to attach the case to whatever mounting solution you wish to use (if any) and then align the vents in the case with the vents on the back of the hygrometer, and carefully push it into place until it is fully seated. 

Make sure to select Celsius or Farenheit before snapping the unit into the housing. 

Updated design with clearance notches in the bezel to allow for easy removal.  Rotate the locking tabs of the thermometer to align with the clearance notches when prying the hygrometer out of the housing. 

I've also included a desk stand in case you just want to use it as-is without mounting the housing to anything.
