Here's an elegant, quick print for the tree. I've provided my PrusaSlicer project files (3MF) and GCODE for a Prusa MK3s+ printer. With my settings, the final ornament weighs very little!

I'll be publishing a new ornament every day! Follow me to stay up to date.

When I printed this in transparent, the only thing I adjusted were seams (from aligned to random) and basic filament settings like hot end temp and flow (Extrusion Multiplier).

If you don't use PrusaSlicer or a slicer that can read PrusaSlicer project files, I've provided detailed print settings on my Thangs Blog.
