Netatmo Sensor Mount (Wind & Rain) for 40x40 Pipe

Mount for Netatmo Wind and Rain Sensor for 40x40mm Square Tube

Mount for Netatmo Wind & Rain Sensor for 40x40mm Square Tube

My Netatmo wind and rain sensors needed to be securely and neatly attached to a 40x40 mm stainless steel square tube – without a wobbly DIY solution, without a zip-tie artwork, and especially without a mount that slowly turns into sad plastic pudding in the sun 😅 So I designed this mount

The best part:
It fits both the wind sensor and the rain sensor equally. If you want to mount both, simply print the part 2x – done The clamp fits snugly on the square tube, holds stably, and the screws/nuts disappear flush into the mount This means: everything remains nicely smooth on the outside, and nothing protrudes annoyingly

Why this model was created aka: "PLA eventually becomes nonsense outdoors")

The previous mount was a purchased PLA version – and it completely fell apart over time outdoors No kidding The material was so degraded that the sensors almost took an involuntary dive Since then, the issue is clear: For outdoor use, please do not cut corners

Recommendation for outdoor use:

• at least PETG
• better ABS or ASA
• with lots of sun, preferably directly UV-resistant filament

In short:
PLA indoors is great – outdoors in continuous sun is more of a brave experiment 🌞🔥
 

What the mount can do

• Suitable for Netatmo Wind Sensor & Netatmo Rain Sensor
• Designed for 40x40 mm square tube
• Clean clamp mounting
• Flush screwing (no protrusion)
• One model for both sensors (print 2x if needed)
   

Assembly (without a nervous breakdown)

The mount is screwed around the 40x40 square tube with a two-part clamp I have integrated a small lock into the flange pieces so that the two parts do not constantly go on a world tour during assembly This makes the setup much more relaxed

Small practical tip:
It's best to press the nuts into the recesses with a short screw before final assembly Saves swearing, saves time, saves nerves 😄

In addition, screw heads and nuts sit flush in the clamp – so no snagging, no sharp edges, no "Why is that sticking out?"
 

Hardware per mount

• 4x M4x60 Socket Head Cap Screws (e.g.: DIN 912, A2-70)
• 4x M4 Hex Nuts (e.g.: DIN 934, A2-70)
   

Printing instructions (from experience)

For outdoor use, please use PETG / ABS / ASA If the part is exposed to continuous sun, it's best to use something UV-resistant

For a nicer finish, you can enable top surface smoothing in the slicer – it really makes the model look good

 

Have fun printing, assembling, and with your sensor-safe outdoor upgrade 😎

And if you would leave a like, a comment, or even a make – that would be super motivating 😁
