To be fair, that is true of all miniatures and model kits. It is generally less noticeable if you are dealing with injection molded sprues as a good pair of nippers can get you most of the way. But it is still good to have some sandpaper to touch things up.
Hell, I use an old pair of nippers to remove supports and overhangs from a lot of my “normal” prints.
… and now I am really curious what a 3d printed runner would be. Might do a proof of concept/experiment in onshape.
I mean, considering that the russians are (alllegedly) calling them “chinese” to be bigoted… that probably IS going to be the official line.
