This part consists of six twisted ellipses arrayed in a circle. Each ellipse defines the shape of a 3D surface formed by sweeping a triangle along the twisted elliptical curve. Although they may look like a single piece, each twisted ellipse is separate. I put all the pieces on a base because I needed more contact with the print bed.

To help visualize how this part looks here's a 32 sec. video: https://youtu.be/TdTLXxjGHbw.

This part printed in 19 hours 11 minutes using a print speed of 80 mm/sec and a 0.200 layer height. To successfully print this your printer needs to be "dialed in" so that it produces no stringing and has good control over it's Z-values. The printer hotend can easily crash into one of the ellipse sections otherwise. Because many of the ellipse sections are long I suggest you set your slicer's Z-Hop (or Z-Lift) parameter to something greater than zero.
