Grandmaster Medallion

I designed this medallion to "disguise" this Manto portable speaker that I'll be wearing as The Grandmaster, so it isn't quite as visually obvious that I'm carrying a speaker around. The design is based on one of the panel buttons from The Grandmaster's party ship in Thor Ragnarok, and would be cool as a sewn-in piece in costumes or as jewelry, especially for costumes based in Sakaar. 

Tip to tip (based on outside nubs) it's 3" in diameter. The outermost circle itself has a diameter of 2.44".
