Adds an extra degree of freedom to a turnbuckle when it is attached to a (chain plate) fixed point.The base drawing, toggle.scad is the intended end result. Base units are in mm, (inches multiplied by 25.4) the toggle core is 3/8 inches wide and 3 inches long, while the corebox is 2.5 inches high and 3 inches long.The pattern drawings contain the split pattern, coreprint, and coreboxes that are actually printed, and used to create a mold.Note that toggle.corebox.scad, contains four components, the corebox halves hang above the toggle and coreprint halves much like bricks don't, and the pattern and corebox each consist of two parts (with locator pins) separated by a very small amount. This layout helps keep all the components at the same revision.The stl's are generated by exporting one component at a time. OpenSCAD's root (!) modifier is a wonderful thing.
