For my mandalorian kit I wanted something from my home planet Onderon, so I came with this badges as part of my character's background. Onderon Rebels were founded by Saw Gerrera during the Clone Wars before moving to Jedha as Partisans (Rogue One).
Three badges are provided:
Onderon Rebels standard: Medium size, flat with hole for a magnet in the back.
Onderon Rebels curved: Big size, curved with holes for magnets in the back.
Onderon Rebels Saw: Collar rank badge wear by Saw himself during the Clone Wars. Stylized and more agresive than the standard one. Small size, flat surface, with hole for a magnet in the back.
Deppending of your printer and settings you'll need more or less supports. The smaller badge doesn't need supports if you print it faced down. The curved one will need supports and maybe a raft.
