A more flexible wall mounted than the one that comes with IKEA Vallhorn sensor.

Have also made a “movement limiter”, if you want to limit the movement range of the sensor.

Have in minde.

Maybe try to scale up or down the wall unit part so the fit gets perfect.

An update to Vallhorn. Made a larger gap between the Vallhorn holder and the buttons on the sensor so that you don't get unwanted button presses.

Happy printing!
