Small tool top open the Gira DualQ smoke detector. Tested with the version I03 of the detector.
Print this with a very small layer size like 0.12 or 0.08mm and 3 walls. Works well with PLA. Print it 4 times.
Keep in mind: Normally a smoke detector is maintenance free and should be replaced after 10years of usage!
