We will see what I come up with, and I will make a youtube video when I have the badges on my 3.
Why not 3d printing? It's easy to make any shape with 3d printing (although metal printing can be a bit expensive, depending on size and what metal you choose; if you're on a budget, there's also metal-coated plastic, metallic paints, and plastic with aluminum dust in it). I love 3d printing services, you can make whatever you want. My only question is, how do you attach it in a durable manner? Epoxy? If you do, you better plan on never taking it off and hope you do it right!
