Our most well-rounded kit for building with OpenBeam! We went through great lengths to figure out lengths that are useful. You’ll notice that the cut lengths often change in increments of 30mm. This is because in a rectilinear framing structure, the 30mm difference allows a piece of OpenBeam to span across the framing structure cleanly.
For example, suppose you have a framing structure made by joining 2 pieces of 300mm (length) and 2 pieces of 150mm (height) into a picture-frame shape. A 270mm piece will perfectly span the gap between the 2 150mm uprights (given that each of the uprights are 15mm wide). If the butt joints were mated the other way, a 120mm piece will perfectly span between the 2 150mm pieces.
