The edges could be a little little bit more smooth (and you can actually see that even on the photos). But that's probably just from the paint application, and nothing what a piece of sandpaper or a small file wouldn't fix. In fact I am unlikely going to bother smooth that myself, it’s mostly a cosmetic aspect rather than any risk for my patch cables.
Make sure you have either the proper 5/8" stand, or the appropriate thread adapter!
