The Empire gets colorful rank badges, but the Rebel Alliance has their own militaristic flair in The Empire Strikes Back. They sport somewhat similar badges, with just slightly different hues. Thingiverse user Jerware came up with a 3D model of the badge and made it available on Thingiverse:
Hoth Badges for Leia and Han. 4-color version designed for the Prusa i3 MMU.
