STEMFIE is a free educational construction-set toy you can download and make using a 3D printer at home. Each component is a part of a mechanical ecosystem of compatible shapes designed to interlock through various connections and fasteners.
The shape and orientation of every STEMFIE file are optimized for 3D printing on a filament-based 3D printer. The STEMFIE project is open-sourced to the community; you can download all files from stemfie.org/download.
As a child, my favorite pastime was playing with construction set toys. I loved inventing machines and fondly remember when my father and I played with MECCANO for hours building the most incredible contraptions. Playfully he gave me the tools and opportunity to experience the joy of being an inventor!
I use various 3D software and 3D printers in my profession. Back in 2017, I started thinking of designing a 3D-printable version of my childhood favorite toy. After carrying this idea in my mind for a while, I started prototyping and defining this new toy's scale and dimensional standard.
The result was the combination of my passion for construction sets and 3D printing, which became a toy I named STEMFIE, inspired by the STEM (Science, Technology, Engineering, and Mathematics) acronym.
My father, Pedro, gave me the joy of being a creator! I now want to share this with you, all the children and makers in the world – hoping that you will find the same joy as I have in playing with it, learning, and most importantly, being an inventor!

- Q: What are the recommended print settings for STEMFIE?
- A: I designed @Stemfie3D to 3D-print optimally, using standard print settings on filament-based 3D printers, such as the following:
- Material: PLA filament
- Layer height: 0.2 mm
- Perimeters (shells): 2
- Top solid layer count: 4
- Bottom solid layer count: 3
- Infill: 15%
- Generic print speed: 50 mm/s
- Q: Should I use support structures in my printer's slicing software?
- A: No. Every STEMFIE STL file is designed to print without support structures.
- Q: How many files, what types of parts will be published, and when?
- A: The STEMFIE project contains many currently tested parts that will soon be ready for publishing. The construction kit has a vast ecosystem of components similar to traditional mechanical playsets. All STEMFIE parts will be gradually published here on STEMFIE.org via get.stemfie.org.
- Q: What are the license terms of the STEMFIE project?
- A: Read about the license here.
