Another quick question (I realize I'm off into what will be part III territory, but I thought I'd ask anyway in case if helps somehow...): should there be a gap between the hot end holder pieces when they are sandwiched around the hot end? I wind up with a 4mm gap once all the screws are tightened as seen in the pictures below.
