Please don't ask me.** ###Summary This is a fun ornament that catches the light beautifully and looks different from every angle. It's part of my [Christmas Collection](https://www.thingiverse.com/dazus/collections/christmas-collection). 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 stren to hang the ornament by. The supports add a lot to the print time. My print time was roughly 11 hours.
