Summary This is a simple model for the construction of various truss related projects. Included here is a round node (1/2" in diameter). I usually print this at 1/2 size (1/2" dia.) and (8) halves at a time (as shown) on a Printerbot simple. The chords I am using in the sample photo are bamboo kabob sticks cut to 2" length. We have designed many versions of this to fit various chord types. We usually print 1/2 of a node at a time and super-glue them together. I've had these printed on shapeways in 1/4 scale and as full spheres. More related models to follow. Added on 1/29/15 - a round chord or stick. 2" long. It's easy to print, and it fits with the kit of click in panels that complement this system. Credit to co-creator and 3D printing mentor - vinchlet.
