Anet A6 Z-Axis endstop adapter for 3mm glass

This thing is a rework of http://www.thingiverse.com/thing:1593629 for the 3mm glass.

Was playing with printing on top of the glass and didn't want to make bed adjustments each time when don't want to use it. I would say, that auto bed leveling is the way to go, but this solution is also works as a temporary one.

Changes can be found on https://goo.gl/2GkvIX

P.S.: Just ordered my proximity sensors, so while waiting them, this solution will allow me to use both glass and aluminium surf
