Posting my Stevenson screen on MakerWorld as it has been very successful on Thingiverse.
This design has gained a lot of interest and sparked a lot of remakes over the years.
Please see the original post here: [https://www.thingiverse.com/thing:2970799](https://www.thingiverse.com/thing:2970799)

If you like to see modifications, adaptations or any other improvement - let me know and I will do my best.

Summary

Sunscreen for outdoor temperature sensor.

update 180626 
Added a screen layer with integrated sensor mount.
 

If you need an accurate reading of the outdoor temperature, direct sunlight and downfall is a problem.
On a chilly but sunny winter day the temperature reading might be 10-15 degrees too high because of direct sunlight warming the sensor.

The solution is shielding the sensor from the sun while not restricting airflow, since the air temperature is what we're interested in.

I couldn't find a sturdy design that was likely to survive a couple of years without replacing parts, so I drew up this. I hope you can make use of it.

Feel free to comment on shortcomings, possible improvements or anything related to this design. I would also very much like to see your installation if you chose to try this one out.

Print as many shield rings as you need for your desired height. I settled for 5 rings (4+top).
Use two pieces of M3 to M5 threaded rod to hold it together.
Depending on how many rings you use, a long wood screw might also work.
Each ring adds 23 mm. The diameter is 124 mm.
 

I made this in PLA in the autumn of 2017 and so far there are no visible signs of it failing.
We had an excavator doing work around our house which knocked it off the garage wall.
I printed a new wall holder and it went up there again, still going strong in October 2025.
So far it has seen temperatures between -20 and +35°C.

Designed to use a cheap Dallas-Maxim DS18B20 temperature sensor in a weatherproof casing, such as one of these: [https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=ds18b20+waterproof&_sacat=0](https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=ds18b20+waterproof&_sacat=0)
You can of course use any sensor you like.

Wall mount is designed to let water and snow out to prevent it breaking from freezing.

Happy printing!
