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

There are new STEMFIE build plates ready for download from this link. In addition, this folder will be regularly updated with new files containing essential components so that you can mass-produce your collection of STEMFIE parts. 

Note that all files contain as many parts as possible, fitting within a square surface. Most build plates are nested to 140 x 140 mm; if the STEMFIE parts are more extended, the 200 x 200 mm, and 300 x 300 mm build plate sizes are used. 

Instead of the STL format, the files are saved in 3MF format to save space. Your slicing software should be able to import .3mf files. 

Enjoy your ready-made build plates and play with the STEMFIE construction-set toy.

The STEMFIE Quick-print Sample file is an easy way to test a few STEMFIE parts and fasteners. You can also check the STEMFIE Calibration File for more elaborate types of fasteners.



STEMFIE is a free, open-source, 3D-printable construction set toy that helps children learn STEM! Download the files freely, and please support my efforts to expand this project.
