Here is Mayor Vaughn from Jaws, designed as a replacement head for an 8 inch clothed figure body (NECA) - connection for ball and socket 'necks' is built into the 'neckless' model. Some sanding of the socket may be necessary for optimal fit with the NECA ball joint, depending on materials, printer, and NECA figure. Dimensions already scaled to NECA 8 inch clothed figure scale - NECA head (no neck): X = 23.37mm, Y = 29.51mm, Z = 33.66mm. Designed for printing with 3D resin printers (for detail), but heads will also print on many FDM printers.
