3D Printed Straw Connectors V7

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 three straws in a vertex so that each straw is 60 degrees from the other two, this way you can build tetrahedrals and other shapes from equilateral triangles.  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.
