You never realize how useful a 3D printer can be until you have a 3D printer. The tailstock for my 1941 South Bend lathe did not have way wipers on it. The way wiper clears away junk on the ways (where the tailstock slides) preventing that junk from getting under it and damaging the ways. So I drew up and made a set of way wiper covers that I will mount on the tailstock with machine screws. I even incorporated some oil passageways to occasionally add more way oil.
