Saving individual model parts?

Greetings. There is an issue I can’t find solution as for now. I want to save a piece of my model as a different file object so I can recover and import the original piece after I make several changes to the former and create new ones. Is there a button or a hidden menu to accomplish this?

Export the object to another format such as .obj or delete everything except the object you want as File / Save As

Hmm, that makes sense, yes. I thought they added an “export selected” or “save selected” button around but looks like the program lacks that. Thanks for the heads ups.
