Subject: [PATCH] Resizes reels. Was 99mm diameter and works in larger
 patersons but not the standard 2 reel model. Resized to 94mm to match the
 standard reels. Removed a single rotation of the spiral. Should fix the
 spiral implementations to accept a desired length, not just an integer of
 rotations.
