The article outlines a methodology for creating three-dimensional object models for a standardised approach to STEM (science, technology, engineering and mathematics) design. The study was conducted on the example of tightening the vertical levers of a freight wagon bogie. The features of the tightening design as well as the strength calculation for the rod system are described. Its loading under the action of an external force was simulated using the finite element method by means of the SolidWorks simulation software to determine the stress distribution and displacement fields in the tightening. A 3D-printing of the tightening prototype was carried out, which confirmed the accuracy of digital models and the effectiveness of additive technologies for their creation. The achieved results showed the potential for using 3D-printing to test and improve wagon brake systems. The presented methodology has practical significance for mechanical engineering, transport systems, and automation, as it can be used to reduce design and production cycles and increase the product competitiveness.
