Arcade control top for Happ Sanwa

I was looking for a simple replacement for my 4 cabinet arcade machine that had the basic red oblong handles. This topper is a sphere 44mm in diameter. They have a threaded hole modeled into it, but I still ran a tap down it to give it a perfect fit. These two were printed with SLA in a translucent blue color from Sunlu. When wet they were nearly perfectly transparent, so by way of polishing or possibly just a clear coat you could likely get them to a clear state. Should work for FDM prints as well. For FDM I would do at least 4 wall layers so the tap has something to bite into without making that inner hole too thin.  SLS just print as normal and run the tap.
