The author remixed this model.
This design is a rebuild which was inspired by Denis' design.
I was unhappy with the fact that the original model closes off the back of the sensor, which is where the data is collected from. As such I did not feel confident in overly trusting its readings.
I also added fillets to make it look nicer and moved the orientation of the ejection holes so that the Hygrometer is naturally inserted in the upright position.
There are two designs to choose from, though I personally ended up using the Radial design.
