A 3D printable protective housing for the CloudWatcher weather sensor. Shields the optical and electronic components from bird fouling, heavy rain, and direct sun — while keeping the sky clearly visible to the sensor.
Protects your CloudWatcher from bird droppings and rain splatter while the louvre design maintains free airflow and an unobstructed view of the sky. Suitable for permanent outdoor installations.
Print in PETG or ASA for outdoor durability. UV-stable filament recommended for roof installations.
This design was created by CloudWatcher user William B. after more than a year of real-world testing. It addresses three recurring problems with the older external sensor modules: water ingress, insect contamination, and solar heating — while adding an optional anti-bird spike platform.
William generously shared the design with the CloudWatcher community. The files are provided free for personal and non-commercial use under the Lunaticoastro 3D Designs Licence.

Each part serves a specific function. Print them separately and assemble with standard M3 hardware.
Base
The main body that mounts over the CloudWatcher sensor. Provides structural support and cable routing.
Cap
Top cover that protects the sensor opening from direct rain. Designed to shed water without blocking sky view.
Louvre
Angled slats allow airflow and maintain a clear sky-view angle while deflecting wind-driven rain and splatter.
Mesh Holder
Retains a fine mesh screen to prevent insects from entering the housing and contaminating the sensor.
Anti-Bird Spikes
Printable spike array that clips onto the top of the assembly to deter birds from perching on the housing.
