I slightly modified motoi1484's Apple Magsafe2 holder to fit my 13 inch late 2012 Macbook Pro Retina 13 inch model. This object is to be used with a MagSafe to Magsafe 2 Converter like this: http://store.apple.com/us/product/MD504ZM/A/magsafe-to-magsafe-2-converter The object holds the power connector and converter very snugly. If you use an actual MagSafe 2 power adapter with your 13 Inch Retina MacBook, please download this object instead: http://www.thingiverse.com/thing:409859 Now the power connector doesn't fall out every time I move the Macbook. Thanks to motoi1484 for making the original design. NOTE: Please use caution when attaching this object to your MacBook as the screen will NOT close when the holder is attached. Use at your own risk, I assume no risk if you forget to remove the holder and damage your device.
