Not only does this kit contain the same parts as the OpenBeam Precut Kit 1, it also includes motor mounts and other parts needed for building desktop CNC & 3D machines.
This kits comes with everything you need to start building rigid enclosures (with added acrylic/wooden walls), frames for 3D printers & other automated equipment, camera rigs, or a robot chassis. OpenBeam precut lengths make it so quick to start building mechanical structures that easily combine with electronics to make all kinds of interesting projects. Not only can these projects be built in record time but they can also be easily shared. If anyone else wants to replicate your shared project, they can pick up this precut kit and quickly create their own.
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 x 150mm pieces.
