Dial Indicator Mount - Sheldon XL

This remix changes the block to fit the height clearance that my Sheldon 10" XL needed on the ways and adapt the holes for M5 hardware.

I also removed the holes for the heated inserts. I use a 75mm screw mounted from the bottom and an M5 wingnut on top to easily adjust the position. I believe the dial indicator is mounted with a M5-15mm bolt, but it might be a 20mm.
