Beautiful candle holder with lovely decorations.
One-Mesh files are easier to slice and print, full-geometry files with all bones are nightmare to slice and impossible to print with many small overhangs.
But don´t worry I decided just to print full-geometry without support and it came out as you see on pictures. I just smoothed some hairy areas with a lighter, looking decay.
Some bones are breaking apart if you touch making it more scarry...
All versions meshes sliced fine for me with cura.
Standard is version on picture I printed, TotalOverkill is double bone count.
