This dial indicator slider is built on top of a phone clamp that allows a quick way to setup dial indicator without messing with the hotend.

My measurement was a little off on the dial indicator mount (for Turlen brand, but it fits) and height of the bracket was too low to clear the screw nuts on the underside of X axis frame. So I just epoxied another set of brackets on top of them. STP files are included, feel free to improve it.
The bracket with PTFE must be a perfect fit to the thickness of X axis frame. My M2 is the first generation from 2013. Measure twice and print once.
Print four pieces of sliders and the dial indicator mount. Screw the mount to the phone clamp with 1/4"-20 screw and epoxy the brackets as shown in the picture. Finally apply PTFE on all three interior walls of slider.
Move the print head to the far right and attach the clamp on X axis frame.
