About this 3D model

This is a variable length and ring AR printable form of a chainmaille weave coined Jens Pinds Linkage. More information on the weave itself can be found here: http://www.mailleartisans.org/weaves/weavedisplay.php?key=335 The math for this one was interesting, as the changing ARs cause the angles to change. It turned into a very interesting parametric geometry problem after identifying that the angle needed to be changed depending on the AR.
