3D printing is also a hobby of mine,,,designed and printed some end caps with a pocket for the knot. I think they will help me with some of the snags. They are a little larger and about a gram heavier than the normal ones. Will be a little more difficult to adjust tension because the tails on the knots need to be removed. Made some LE tees with angle to match the kite, printed on left. Whats cool about printing these parts is the frame size or most any other parameters can be easily adjusted. What do you folks think ...
I may be putting some of these files on Thingiverse at a later date, not sure, still tweaking them now.
