  • I noticed that two of the annular rings are actually squares. Why is this? I thought at first maybe it's to mark which ones are ground, but only one of them is a ground. So why are two of them square? And what do you call them? Annular squares? Rectangular rings? I see them in pictures on other boards, too.

No public wish lists :(
