Amoraph

Amoraph, a flower vessel torn from another dimension.
Partly non-orientable and similar in nature to Phamora, but this is a true Klein variant.
While the body is traditional, the top loops back on itself and rejoins the body without thinking twice.

I entered this model in the GrabCAD Figulo challenge and it won!
:-D
You can still grab your copy from GrabCAD.
