This is technically one of my “Swoop” designs, but it looks like diamonds to me (or the Eye or Sauron, you pick). This ornament looks great in any color – solid, rainbow, multi-color, transparent, or glow-in-the-dark.
There is one more ornament in this series – a topper. I'll be publishing a new ornament every day this season! Follow me to stay up to date.
I've provided the finial as both one piece and two. It's too large to print on my printer in one piece, so I cut it in the middle between the two bulbs.
If you plan to print the ornament in two pieces using two color or rainbow filaments, I recommend printing the two pieces together as I've done in the provided PrusaSlicer project file and GCODE (for a Prusa MK3S+ printer). If not, I recommend printing the two pieces separately to reduce stringing.
To glue the pieces together, I recommend using a slow medium CA (super glue). The best way to do it is by placing a roll of filament on an inexpensive Lazy Susan. Then, place the top half of the ornament upside down in the center of the Lazy Susan. Align the ornament so it's roughly centered on the Lazy Susan and vertical, place a drop of glue at the joint, and attach the bottom half of the ornament. Gently turn the Lazy Susan and adjust the alignment of the two pieces of the ornament until you're happy.
