Aqara Temperature and Humidity Sensor - Outdoor Case with Magnets

A simple outdoor housing for the Aqara Temperature and Humidity Sensor (Zigbee), based on the case from Andos. The case fulfills its purpose and protects the sensor from wind, rain and direct sunlight. It is also relatively compact, not very noticeable and can be printed relatively quickly and easily. However, I was annoyed by the four screws, because even if the battery lasts a long time, it still has to be changed from time to time.

I reworked the model just a bit. I only slightly reworked the body itself and added a few chamfers and fillets to make the edges less hard. The housing can either be attached with adhesive tape (like the original model) or with four small (pan head) screws (screw up to 3 millimeters, the head a maximum of 4-5 millimeters wider).

The lid is hold to the housing by magnets. I have uploaded models for magnets with 5x2 millimeters and 6x2 millimeters. The magnets are slightly raised in the housing for better positioning. It's even better if you glue the magnets in the other way round so that you can only ever attach the lid in the correct orientation.

Print settings:

No special print settings are needed, but the holes for the magnets should ideally be printed with a layer height of 0.2 mm. Tolerances are 0,2mm.

The housing can be printed as you want. I have set a variable layer height for the lid so that the upper rounding is printed more smoothly. Supports only for the holes. The "windows" can be printed without supports, they just need to be cleaned a little. With supports, the result is almost identical, but you have to clean less. ;-)

Print material:

Which filament you use also depends on where you want to attach the sensor (no sh*t, Sherlock). If it is only hanging in the shadows, PLA or PETG is possible; if the sun shines on it in summer, it should be at least ASA/ABS. PETG-CF is also possible. But avoid dark(er) colors, as they absorb more thermal energy ;-)

I redesigned the housing a little, added four screws for the mounting and the lid is now held in place with magnets instead of screws.
