This work aimed to use a 3D printer to develop material that contributes to the teaching process of Combinatorial Analysis (specifically the Fundamental Counting Principle) to blind students. Even though Combinatorial Analysis is a content with varied practical applications, there is a lack of manipulative pedagogical materials suitable for teaching this content to blind students. The Combinando material was modeled and printed considering an understanding of the use of manipulative materials in teaching blind students, associated with 3D modeling and printing. Based on this material, a task proposal is presented to work the fundamental counting principle with blind students. The task will be guided by discussions about Combinatorial Analysis, presentation and explanation of the material, delivery of the activity and material, setting up groups, developing and discussing the task. The pieces of material have reliefs that allow them to be identified by touch. It is also possible to differentiate the parts visually, since the material has overlapping colors. Thus, blind and sighted students can explore the same material together in an inclusive manner.
