Summary

I wanted to have an outdoor ornament so resized the design 3x.
Also I noticed the original did not compensated for the angled assembly, which would exacerbate when up-scaling, therefore I remodelled it with proper angled slits.
And lastly to save on filament, I downsized the thickness for all, but the slits (snowflakeS.stl).

The coloured ball is of original size.
