After several prototypes of making printable spring, I found this to be a nice approach with good quality and easy post processing.

###While editting the Fusion 360 file parameters, keep an eye on the last slot opening commands, because it might need adjustment. ###The spring deform slightly after repeated action. If you want better durability, increase the spring density by reducing the pitch.

###Standard printing procedure: Loads the Spring 11x60.stl in slicer, 0.2 layer height, no support. Print.

Load the coil and support separately if you want to set the wall thickness differently to save material.
