On a Lotus Elise S2, there are six plastic couplers which connect the front brake lines to the ABS cables, assuring that the ABS lines are properly routed. When replacing the OE brake lines with stainless steel aftermarket lines, the OE couplers are too loose and can't be used. These replacements will couple the ABS lines to aftermarket stainless steel lines made by Inokinetic and others.

There is a swiveling ball joint bewteen the two ring clips. It was designed so that it will spin freely when printed at 0.2mm layer height using either PLA or PETG. Other layer heights and materials may work, but have not been tested.
