The 2nd and third stages of the Saturn V had the LH2 supply lines go around the LOX tank and are visible between the skirt and the J2 engines. The attached STL files were printed using a Creality Halot Mage resin printer as the detail is finer and the fragility of the resin model is not an issue. They are made in 1/72 scale and a bit longer than necessary to allow trimming to fit.
