I’ve just uploaded the models for the US Navy Submarine Patrol pin. This is a pin that has holes for stars to be mounted, so stars are included separately to be added in whatever is the appropriate number for your application. One note, these stars are numbered 1 through 6 from right to left and are configured with proper height and angle to fit in those holes only. You can probably swap a few around and may even be able to get away with going from left to right but they’ll look best going right to left.
The current queue is Enlisted Expeditionary Warfare Specialist badge, USMC rifle and pistol marksmanship badges, Combined Explosives Exploitation Cell, Army diver badges.
