This are all required parts for a drill-free mounting of the Dust sensor box in the outer frame of a window.

There is only a tube with an outer diameter of 18 mm needed and some M4 and M3 screws.

To clamp the pipe brackets on the pipe I used threaded bushes.

The tube parts can be sawn as they are needed.
