Indication Paper on multiple autonomous

Just as clarification, is it legal to have a small sheet of paper covering the potentiometer part of our autonomous selection system? There’s a hole in the paper for a shaft to go through and a sprocket on top. We use the sheet of paper to help indicate where the sprocket on top of the dial is pointing at. It doesn’t bind any parts of the robot together, but it would be taped to the potentiometer.
