Dial Indicator CNC Spindle Mount 52mm

thingiverse

This will enable you to temporarily attach a standard dial indicator (with mounting lug) onto a 52mm CNC spindle to assist in leveling the spoil board relative to the machine's XY axes. I used a 1/4 inch screw and nut to mount the gauge to the clamp, a #10 or an M4 or M5 should work just as well. The thumbscrew employs an M3 screw and nut. A 1/8 inch screw may also be effective, but you might need to secure the nut with a soldering iron.
