UPDATES! The following video is a continual improvement of my version posted here. It has been called MagSavior - The Apple Magsafe Adapter Saver. The new version is posted in both Thingiverse: http://www.thingiverse.com/thing:154463 and Indiegogo website: http://www.indiegogo.com/projects/magsavior-save-your-magsafe-power-adapter. Please have your support by contributing to our project. Thank you.
Have you ever encountered your MagSafe power adapter for the MacBook blown away suddenly one day and you have to buy another one? Have you noted that the joining part of the adapter and the cable have a kink in it? That is because the negative shielding has worn off. (See my photo attached!) Thus will create lots of electrical stress onto the adapter and one day you will hear the "POP" sound.
If your MagSafe is still working and wish to prolong the life span before googling "How to fix Magsafe adapter".
I have made this little clip that is able to strengthen the flexible end of the joining part between the cable and the adapter.
I have posted on thingiverse on two types. One original and one remix.
