Aqara temp. sensor holder for ventilation unit

I always used duct tape to fix my aqara sensors inside my Paul Novus ventilation unit but I was worried that they would come loose and fall into the running engine. I now made this conical holder so the sensor can definitely not get loose. Also handy for replacing the battery. The diameter of the ventilation tubes is 16 cm. The diameter of the aqara temperature sensor holder starts at 15 cm so it fits nicely. Best printed with supports.
