Nick, that's a drawing created in a 3D program, Google Sketchup. I did not make any prototypes of that design, but did make (at my local machine shop) some prototypes of the one shown here with the other one. I will post some photos of the actual cap in use as soon as possible. Flew them on sand at the IKE retreat this past weekend for two days on sand. Flew another kite with standard caps as comparison. They are awesome. Not a grain anywhere.
