These are my Prusaslicer settings (and the gcode for Prusa MK4) to print this model in an optimal way.
With these changes, it can spin over 2 minutes.
In order to maximize momentum and stability, it uses 100% infill for the tip and the first half of the base, then switches to less dense infill with the concentric pattern. Finally, the handle doesn't use infill in order to reduce its weight.
Includes the supports and brim, so ready to print.
The author remixed this model.
