I was talking to a friend who has a Delta printer that he built. He said, “I wish my Delta had a build plate that I could level the old-fashioned way” This got me thinking how hard could that be? I had a “nothing planned” weekend so I wondered what I could do and then I remembered what he said and decided to give it some more thought. Below is how I made an old style calibration option using some springs, a visit to Tinkercad and a few thumb screws for my Delta 3D printer. Fi
