This article presents the technology of 3D design of fire detector body parts
using the CAx system. During the 3D design of the components of the fire detector, its
design has been improved, and its operation is ensured on the basis of the Arduinomini
board. The production of the lower cover of the fire detector for the Arduinomini board
is realized with the help of a 3D printer. At the same time, a thermal analysis was
carried out in the CAx Fusion 360 system of the improved fire detector design.
