I remixed the Macbook 85W charger (created by naterules) in order to fit the new Macbook Pro's (2016) 87W charger with a USB-C connector. The size of the adapter itself hadn't changed, but the smaller cutout needed to move to a new location. The model's polygons aren't as clean as the original, but was repaired and doesn't have any internal or external differences when printed.
