I really like the design of the platter and its piercings, but felt it somehow looked a little heavier than what I'm used to seeing. I don't do any piercing work, so I wasn't commenting on it as I certainly couldn't do as well, let alone any better. I take my hat off to you for coping with a Dremel on an 8mm thick substrate; from the demos that I've attended, most of the professionals start off with 2mm wall thickness.
