The hinge on my x200 Tablet snapped off at the metal bracket between where the hinge connects to the screen casing. This part is designed to slip on top of whats left of the metal bracket and attach it back to the screen casing.

Note: Many of the tolerances have been purposely made loose because I had to make this file on my laptop, if you have time and filament I would highly recommend tightening some of the gaps to improve the fit.
