3D Printed Straw Connectors V2

As a follow up to my previous post about a 3D printed straw construction set, I've made a new shape of connector.  This new connector  joins straws at 90 degree junctions, this way you can make a cube or other shapes with right angles.  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.
