There's still some servo mount material (the servo screw with rubber grommet) sticking out about .5mm-1mm from the aluminum brace. I already trimmed the rubber away since it was sticking out a lot more and was pressing against the belt initially, but are tolerances so tight around the belt that it would rub the aluminum servo mount even without a servo installed? I still am thinking the belt itself was one part of the issue since it didn't lay flat. There was always a part of it that wanted to twist. I know it's thin, but still.
