Abstract	We propose an apparatus that emulates the experiment used by Geiger and Marsden in 1913 to investigate alpha particles (Rutherford) scattering. Using a widely available fused deposition modelling 3D-printer, we built a compartmented and easily assembled educational instrument. The whole apparatus is composed of a 3D-printed chamber and an electronic box. The chamber emulates the alpha particle source, the gold or aluminum foil, and the Geiger detector, which permits a real interaction by the students with the experiment simulating the real one. The electronic box has an Arduino board inside, which is responsible for simulating the particle count as a function of the scattering angle. The results obtained for gold and aluminium are similar to those found using a commercial apparatus. This low-cost didactic apparatus can be mimicked or improved from a source archive (both 3D model and Arduino project), which may help spread chemistry and physics concepts in a ludic but effective applied point of view. (As Provided).
