STEMFIE is an open-source construction set toy system[1][2][3][4][5][6][7] and brand[8][9], made out of 3D-printable plastic bricks, that are connected using screws. This construction set is designed with 3D printing and its limitations in mind. In contrast to Lego bricks, the CAD-files for the individual STEMFIE parts are available as open-source on GitHub and the STEMFIE website[10], licensed under CC BY.[9] Using the bricks, you can build projects, like a functional rubber-band car or a catapult.[11] The STEMFIE construction set was created by Paulo Kiefe[12] on 21 December 2019[13], who is also the co-creator of the 3DBenchy.[14][15] Paulo Kiefe presented STEMFIE at the Printed Worldconference 2025 in Amsterdam, Netherlands.[14] All STEMFIE parts are designed in the open-source CAD software FreeCAD.[16]
