3D Printed Straw Connectors V6

Intro: 3D Printed Straw Connectors V6

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 four straws in a vertex.  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.
