The square beams, measuring 12.5 x 12.5 mm, are the most common and valuable parts of the STEMFIE construction set. Combined with braces and using the corresponding fastener length, one can already create complex structures.

All 3D files of the straight beams with square endings are now available for download. The range of sizes for this part release measures from the tiny 1x1x1 block units (12.5 x12.5 x12.5 mm) to quite long 50 block units, measuring a length of 625 mm!

Browse all the beam files and download them from this link or the corresponding file repository at

I'd like you to stay tuned for more part releases shortly. Also, please follow STEMFIE on social media and in the newsletter.
