You definitely don’t need a layer height that low for something like this. Even still, you’ve got something set up weird because at a normal 0.2mm layer height it’s showing just under 4 hours to print everything but the pull rods (only because I’m too lazy to split the STL apart right now.) Try resetting your build settings or start a ‘new’ project.
Don’t use Creality Slicer, it’s just an outdated renamed version of Cura. Download the most recent version of Cura here and your problems will most likely go away. https://ultimaker.com/software/ultimaker-cura/
