The current design of this protective case establish a stable connection from sensor to soil. Even when it is capacitive sensor a permanent contact to soil is neccesary for reliable moisture values. Examples of these values are shown in file Sensor_1 and Sensor_2.

I recommend using PETG for its elasticity. Support is needed for the ring. All screws are M3x10 cylinder head screws. 

Seal the cutting edges of the moisture sensor before mounting it. This is important, otherwise the epoxy of the sensor will absorb moisture and disturb the moisture values. As seal you can take nail polish or similar with low consistency.

Now version 8 is available. Therfore I updated the folder structure for a better overview.
