It’s going well so far, I haven’t really compared it to my other collars but it’s hovering around 2700 triangles at the moment. Those extra beveled borders are (probably) responsible.

I don’t really like how those 8 sided rivets look, I might bump them up a little. Likewise, the bushing around the lock hole looks a little dense… do I even need to model it?

Both halves are identical at the moment, the only difference is that one side is upside down. I might keep it that way, surely there is no reason to duplicate that model.
