looking for an old IBM knob from a 609 calculator panel

 Even with 3d printing, you'd need to do some  sanding and shaping to make it look as clean as the original. I still think casing one is the best option. If the mold is right, it will even match the surface.

Yes, it's a standard 1/4" shaft. Might try and get one 3D printed if I
can figure out how to draw it.
