A utility to map extruded lines/objects/shapes to STL files. For example, say you have an STL of a curved vase. You want to add a spiral to it. So you place the photo of a spiral on the object. The utility lets you decide where on the STL it'll be placed, then you can decide the extrusion depth (positive or negative).
Possibly including some type of LLM, too. So you can import your STL, then type something like "picture of the Simpsons in the style of ancient Greek amphora vase paintings." It'll appear as line art on the 3D object
Note that I don't need this, myself. You want to work on something interesting, so I thought for a few minutes and came up with this. :)
