I think, the lines don't cutpath=CIR.

Using the intersections library, the code would look like this (I have highlighted in red the required line):
documentclass[border=2 mm,12pt]standalone
usepackagefouriernc
usepackagetikz
usepackagetikz-3dplot
usetikzlibraryintersections
colorletbgcolorwhite
tikzset
overdraw/.style=preaction=draw,bgcolor,line width=#1,
overdraw/.default=2pt
