I recently asked a question (Is there any public and reasonably accurate 3D scan from a Cray-2 computer?) about where to find (if there is any, because I tried and there seems not to be) a 3D model of a specific object I could use as a starting point for printable model and printable parts and it was flagged as off-topic and closed. Has this type of question proved to be troublesome in the past?
This topic is actually up for debate possibly. I don't personally know if this sort of question has been actually troublesome. I remember your question well and whilst it didn't fit into the scope as it is currently defined, it seemed (IMHO) a reasonable question nevertheless. It was unfortunate that you did not get a suitable answer before your question was closed.
I have include this question in the new meta post about what should and shouldn't be on-topic, Game plan - What is on-topic?.
mostly this is an off-topic question, as per question rules - click
That means your question is not about solving a technical problem.
