I modeled this head so that I could create the Drum Major Helmet and found that it actually snaps onto torso and wears a hat just fine as well.  So, sharing with the universe.  :)

Print oriented as-is without support.  Snap-in dimension tolerances and thresholds are suitable for a consumer-grade resin printers (about .1mm resolution required).  Still, I had to use a drill to hollow away the excess resin at the inside nape of the neck before snapping it onto the pillar of a standard Lego torso.

If you found this useful, it would bring me great joy to see your work - so be sure to share. :)

You're welcome! (in advance) :D
