The Hanna pendant or Chandrilan medal of freedom is often worn by Senator Mon Mothma is Star Wars. You will find here the various versions of this pendant she is seen with :
- Star Wars episode III : Revenge of the Sith
- Star Wars the Clone Wars animated serie
- Star Wars Rebels animated serie
You will find for each version 2 objects to print : the pendant itself, and the corresponding shoulder brooch (this should be printed twice).
They need to be link together with a metallic looking wire. I didn't put any attach system on the back of those 3D model to allow the system you prefer. Eventually, a system of magnets glue in the back of the elements and in the inside of the robes could helmet make it easily removable and/or stay in place when hanging.
