3D printed mid 20's AC Speedometer wheel yoke

I submitted the following post on the main technical page to try to reach a broader audience.  Posting the link here as well because this pertains to our Buicks and always great input from our group.  Please note that this part came from Larry DiBarry as he had one of his students draw this part as a classroom project.    There were several hurdles to be overcome, not the least being that the part would change in dimensions based on the humidity.  Darn pot metal.  So I had a couple of these made, but now I need a little support to improve on a great start.  Hugh
