Thanks guys.
But the beheaded, permanently affixed Astromech on these designs always bugs me. I still can't get used to it.
Yeah, I was on the fence about including it. Structurally, there wasn't a great way to make spot for a complete droid. Aesthetically, I preferred it to the exposed studs, or a tile/plate of some kind... but I could have easilly gone without it. It was the last thing I added, and it does bug me too with it being on a sloped piece.
