My brass cover accessories came out pretty good. The mustard spread a little ruining the reason I but it on there, mostly. It was supposed to be a letter "Z". So, I formed a Z out of copper tubing and am currently fuming it with ammonia and salt. Will post once finished.

I'm quoting myself for context. The "Z" stands for 'zipper', which is what a piece of the battery retention systems looks like (more specifically it looks like a zipper pull tab, but that doesn't flow as well...).
The copper is a smashed piece of tubing. I did a more aged (bronzed) rather than a patina look. This was the best color correct I could do, quickly on my phone.
