👉   Play freely and build endless fun at home with STEMFIE, the free 3D-printable educational toy   👈 

After two years of development and beta-testing, this new construction set toy is almost ready to be publically available for everyone! 

STEMFIE is a new extensive ecosystem of modular parts that can be freely downloaded and produced inexpensively by anyone with a 3D printer. This educational toy is, therefore, perfect for use within STEM classes and for anyone who wants to learn technology by playing.

The STEMFIE components connect and function within a predefined modular dimensional standard. Each 3D file's orientation and geometry are optimized for manufacturing on affordable 3D printers – as commonly found in schools and homes.

The first project and downloadable STL 3D files will be released soon. So stay tuned and be the first to know when to get them for free by subscribing to the STEMFIE newsletter and following this new toy on social media and popular file-sharing sites.

Download and 3D-print the sample file

As a first teaser, the image above shows a preview of the two most common fasteners used to join parts in this new toy. You can download the STL file for the sample parts in this image and try it on your 3D printer. Please share your results and tag them with #Stemfie3D. :)
