Connect these beams together with Construx-compatible knots:

Standard knots: http://www.thingiverse.com/thing:1254359
Hinge knots: http://www.thingiverse.com/thing:1249866

These endure a lot of stress, so they tend to break pretty easily. Use ABS to give yourself the best shot of using one in a structural role!
