The design flow,
1) I used the torus generator to create the ring and to offset it from center
2) CopyOffset, Pivot (This Pivots around the center and since the object was offset it created this #nice_organic_design)
3) Merged Objects
4) Stitch & Scoop, Union
5) Made two copies and scale them proportionately
6) Merged the copies
7) Magic Fix.
I first merged the objects because of the Stitch & Scoop is not designed to handle so many objects at once but this was only helpful on the first set.
On the second set, The object was already too complex and so Stitch & Scoop was no longer an option, so I used the great MagicFix tool and it worked it's magic! Checkout how this object was made : https://youtu.be/mg-I-1dH4ag Designed and uploaded with www.selfcad.com #selfcad #print-with-selfcad
