Aqara Sensor Outdoor Ziptie Mount

I used the clever mounting mechanism of mdkendalls model and put it into a little case. This model uses two parts, 1st is the mentioned case for the sensor and the 2nd is the stationary mount on the railing fixed with zipties. 

I constructed it like this, so that the sensor could be detached for changing batteries while no new zip-ties needs to be on hand. The little lever on top can be pushed so that the case can slide out on the top. 

I've printed it in PETG.
