About this 3D model

My old MacBook Pro's battery is almost dead. So I need to keep power connector always on to prevent shutdown. So I make a holder to lock the MagSafe on my Mac. This MagLock is inspired by MagStay (http://www.thoughtout.biz/products/MagStay-PRO.html) It will prevent Mac MagSafe Power connector accidently disconnect. The MagStay will occupy one USB port which makes it less practical to use. So, I come up with MagLock which allow me to use the USB port next to the power connector.
