It's a spinning top optimized for a good runtime, but without the need for additional parts (like a ball bearing for the tip). My best run was two and a half minutes.

Print with 100% infill and random seam placement.

Sanding the tip helps a lot. Try to get a nice rounded tip in the center of the tip part.

Optional printing tips: 

  • avoid crossing perimeters (if stringing is an issue) 
  • split into objects, add modifiers for the two parts:
  • main body: variable layer height to add finer details for the spokes, might help a bit with air resistance.
  • tip: 0.17mm layer height (for smoother screwing);
    0% infill, 0 bottom layers, 3 perimeters to reduce some dead weight.
  • —or— use the 3mf file in PrusaSlicer, where all that is implemented
