There are so many hobbyist 3D printing things I’d like to do around my abode by taking some existing piece and tweaking it. Creating a model for a one off part is pretty tedious though.
I think the bar is even lower than that: generating sane STEP geometry from STL files generated by other CAD software is already a huge win. Autodesk Fusion pretends to be able to do that, but it only works for easy demos.
