This is a general purpose truss structure OpenSCAD library which can be used to render structures familiar to everyone from construction tower cranes. When printed, these are very stiff and strong when considering their light weight.

There are two basic structures: a box truss with pyramidal struts reinforcing each box section (number of sections is parametric), and a triangular truss, meant to be a horizontal component. Optional modules offer bolting points to attach several box trusses together to overcome print volume limitations. Triangular truss allows creating a structure which is stronger at one end, weaker at other end, and scaled dimensions and thicknesses in between.

Examples STL:s are included for the basic building blocks. The .scad source file in the zip file documents the various parameters for the primary modules.
