Hobie Pad Eye

11/21/2023 I found that Hobie used a custom design thread pattern on their pad eye hole plugs. These are not a standard thread but in fact are a half thread shaped like a triangle with the wide part of the triangle face the eye and the bottom part of triangles (angle) facing down toward insertion point. The plug has a slight taper. The thread is not a normal pattern and was difficult to figure out how to do it.

I haven't printed one yet and I will tomorrow to test it against the original.
I have noticed I forgot to two notches on the top face for using a spanner to install them.
I will fix that and reupload.

11/22/2023 Just uploaded that modified drawing / stl file with the spanner slots
