After a lot of trial and error, I managed to finish the etch. The tiny endmills needed to get all the detail just didn’t hold up so I had to bump it up after I snapped a few. In the end I don’t think it hurt the design too much and am happy with it. After that it was paint and sanding — I use course sandpaper to give the aluminum a brushed finish that I think looks and feels great. Got everything boxed up except have an issue with the template for the input and output jacks being off (or maybe my enclosure was off) so the jacks don’t really fit. Still debating on whether or not to enlarge the hole or get different/smaller jacks to make it work. So close.
