Recently, 3D printers have been used increasingly in school education because of the performance improvements and cost reductions they yield. However, there are problems to be solved, such as the timeconsuming aspects of printing and difficulty acquiring the operational skills necessary for the 3D-CAD. Therefore, in this research, we practiced an approach aimed at reducing such difficulty by utilizing the design method for the selection of parts appropriate for using 3D-CAD software to teach fourth grade (primary) students. The production theme was a compact “spinning top" to be evaluated by the students, who were to manufacture it and turn it themselves. It was possible to print in a relatively short period of time since the work to be produced was small. Results of our research indicated that students’ interest in the 3D-CAD, manufacturing, and 3D printer were enhanced as they achieved adequate skills for operating the 3D CAD in a short time. They understood that digital data could make duplication and correction easy.
