Welcome to STEMFIE, a groundbreaking 3D-printable construction set toy designed to spark creativity and learning in children and adults alike. Created from a passion for STEM education and hands-on learning, STEMFIE offers endless possibilities for building and inventing at home. Dive into our projects and experience the joy of innovation with every print!

Every STEMFIE file's shape and orientation is 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.


The story 

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. So playfully, he gave me the tools and opportunity to experience the joy of being an inventor!

I use various 3D software and printers in my profession. In 2017, I started thinking about designing a 3D-printable version of my childhood favorite toy. After mulling over this idea, I began prototyping and defining the scale and dimensional standard of this new toy.

The result was the combination of my passion for construction sets and 3D printing, which became a toy I named STEMFIE, a hypocorism of the acronym S.T.E.M. (Science, Technology, Engineering, and Mathematics).

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!

FAQ

  • 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 and what types of parts will be published, and when?
  • A: The STEMFIE project contains many 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 on STEMFIE.org via get.stemfie.org and STEMFIE.org/cloud.
  • Q: What are the license terms of the STEMFIE project?
  • A: Read about the license here.
  • Q: How is the name STEMFIE pronounced?
  • A: STEMFIE (pronounced /ˈstɛm-fi/ 🔈) is a diminutive of the acronym STEM and is pronounced similarly to 'selfie,' which relates to the word 'self.' 
  • Q: How can I help the STEMFIE Project?
  • A: Please visit this page for information on how to support this project. 🙏
