The STEMFIE construction set's most common and valuable part is the square beams, measuring 12.5 x 12.5 mm. Combined with braces and the corresponding fastener length, they can create complex structures.

All 3D files of the straight beams with square endings are now available for download. This part release includes sizes from the tiny 1x1x1 block units (12.5 x 12.5 x 12.5 mm) to the longest beam, measuring 625 mm, at 50 block units!

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