A corresponding cutout of the blade shield.Added slightly more space between the star shaped blade interface and the connecting components (shield and handle)Reduced the recess for the blade in the shield so that it lines up flush with the bladeAdded slight curve to the top of the blade interface so that it more easily contacts the bladeIncreased the chamfer on the edge of the shield so that it does not feel sharpCorrectly set Fuzzy Skin in the print profile.May
