Extruder filament path guide/restrictor for flsun kossel mini

Summary Flexible filament finds it own path, usually the path of least resistance, which usually mean not straight down to the hotend. This is particularly true of the extruder with the flsun kossel mini. This fix literally plugs the hole and provides a restricted path with no means of escape!! Hand tweaked with prototypes to fit my extruder... please let me know if you find this of use and whether it fits. I only ever printed this as a quick dirty draft. your results mat vary...
