Snowtrooper belt gak

Hola Prop persons,
I am looking for the centerpiece of the Hoth snowtrooper belt. It is a round bit with 3 raised circular bits in the center. This is a found object I think as it is also used on a prop I am working on. Sorry not the best pic. Any help on what the real item is would be great. Any snowtrooper builders that would be interested in selling just this part would be great also.

Never been IDed.
It's also on the radio / scanner thing Han uses on Hoth.

Yea I've wasted many cumulative months searching
