As a follow up to my original post about a 3D printed straw construction set, I've made a new shape of connector. This new connector joins straws at 60 degree junctions, and it has a total of 12 connecting points. It allows you to create pyramid-like structures with three equilateral triangles as faces, and attach many of these pyramids together. I printed this connector with an epilog printer (the grand prize in the Make it Real Challenge!) I've attached the AutoCAD and stl files below.
