With a single hotend and without soluble supports this model isn't feasible. You will definitely destroy parts of the geometry by removing supports.
This will remain a work in progress as for now I don't have the time to work on it. I added the stp-file if someone is interested in reworking this.
I had the idea of doing a 3D Ambigram. As Mother's Day is near I thought this would be the reason for doing this :-).
I'm still working on a support strategy for this. Those of you who have a multi extruder are the happy ones. All others have a lot of work to do.
I uploaded the second version of the stl and a video from the first try to show you the whole idea. I lost some geometry while cleaning and didn't finish cleaning so...it doesn't look so nice.
Already printing the next version. Hopefully this will be better.
