3D Printed Straw Connector V4

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.

    Nice !, if you could separate the pegs and joints, it would be lot easier to print. Joints can be simple square with holes for snap fitting the pegs. Also joints can be of different types like square, rectangle, triangle and ultimately sphere with hole on all sides. That way, you can print pegs en mass and joints only when necessary.

    This is awesome!! The kids at the school I work for make things with straws for math and science, the teachers use pipe cleaners to hold them together, but as you can imagine that doesn't work the worlds greatest. These would be such the perfect solution! Nice job!
