Surface 1,2 & Pro 1 and Pro 2 power supply repair.

thingiverse

This design serves as a replacement for the 42W power supply of the Surface Pro 1 and 2 models in case the cable breaks, forcing users to open up the brick itself. To ensure safety, print this model at 100% infill. Be aware that this project involves working with mains voltages and requires great caution. Only undertake it if you're familiar with the associated risks and hazards and are confident in your ability to work safely on such equipment. Verify the polarity of the output connector before connecting it to your tablet. For reference, consult the pinout at http://thomsoneu.blogspot.co.uk/2014/06/microsoft-surface-power-plug-pinout.html
