I figured out the problem with the nose cone. It was a two part issue, while some of the polygons appear to be properly touching in Tinkercad, they really were not, there was a tiny gap. The second issue was a mistake I made in Tinkercad for the wall thickness, it was too thin. I have a little flash cleanup to do on the part from the supports, but prints much nicer now. I also lengthened the shoulder.
