FIELD: teaching.
SUBSTANCE: some of the proposed modular frames can be assembled in the form of three-dimensional modular devices and are particularly suitable for teaching purposes. Modular devices containing two or more frames can be connected by means of locks in two or more different configurations. Containers containing electrically conductive material are also provided and configured to form a Faraday cage around its contents.
EFFECT: modular frames for teaching purposes are provided, they provide a strong fixation of geometric bodies.
