"Inspired by" might be better than "original pot" because as anyone can tell (including you!), they aren't 1:1 matches.

Almost any 3D artist doing objects, especially a new category of objects they haven't done before, will do so with 3 or more reference images from every angle and model based on those, pretty tightly initially at least. But even with that, you add your own style and taste into the modeled object, and almost never will say that what you referenced from is the "original object" in that manner.

"Inspired by" works well though and doesn't remove anyone's agency or lessen their "creation" of it :)
