If you would like to 3D model your build with a CAD program like Autodesk Fusion 360 or Solidworks, here are some STEP files of our connectors. They are simplified, but have all the important dimensions you need. I have attached the T Connector, 90 Degree, 180 Degree, 45 degree, 4 Way, and 5 Way models. We would love to see your designs, so please share them in the community!
