Bumps the preview script to a 960x360 image with a closer camera distance so the label fills the frame with roughly equal margins on all sides. Adds a sym1_pad=2 override for nut+washer renders so the left washer ring sits inside the label edge as before, then refreshes every M2-M5 preview to the new framing.
