MakerBeam, the open-source building set that got its start thanks to 132 Kickstarter patrons donating almost $18K, has released its first schematic. The above design, available as a PDF on Scribd, shares the most critical part of the MakerBeam design: a cross section of its Mini-T beams: with this PDF you could theoretically extrude your own. I’m looking forward to the fruits of MakerBeam’s continued openness.
