I've recently started restoring an IBM 327X 75 key beamspring and I need to replace a few of the stems. Given the price and scarcity of original parts, I would like to laser cut some new stems out of stainless steel, which should hypothetically be an upgrade over the originals. I could create my own model, but if anyone already has an accurate STL or DXF, I would really appreciate it if you could share it with me. Cheers!
