This is a fun ornament that catches the light beautifully and looks different from every angle.

I knew from the outset that printing this would be very difficult, so I accepted it as a challenge and as you can see, it worked!

I was able to get a reasonably rough print by engineering supports. They are designed not to handle overhang, but to keep the print adhered to the plate and eliminate any wobble in the x-y plane. They release easily with no marks on the print and no cleanup. I've provided the model with and without these supports, but without something that acts like them, the I believe print is impossible using an FDM printer. It may be easier to print using resin or another technology.

I improved the print quality by using Cura's "Custom Supports Cylinder" plug-in to add 10mm cylinder supports under the center of each wide, unsupported section at the top (shown in slides). These reduce warping on the Z axis.

There's a tiny hole at the top of the ornament for you to insert a thread of to hang the ornament by.

The supports add a lot to the print time. My print time was roughly 11 hours.
