Homematic windows / door sensor clipon

thingiverse

I carefully crafted these beautiful Homematic contacts so they wouldn't require any holes in my delicate wooden windows. Since drilling is not an option for me, I came up with a clever solution - this clip. It attaches snugly to the window frame without leaving a single mark. To ensure a secure fit, you can apply some glue directly to the sensor and attach it right on top of the frame. The result is a tight seal that doesn't need any screws or tape.
