Two-up Leveling Gauge Mount
A simple dial indicator mount for use with the QU-BD Two-up. Just slip it over the end of the extruder stepper and your on your way to a precision leveled print bed.
The recommended dial indicator is a Pittsburg 1" Travel Machinist's Dial Indicator, item 623 on Harbor Freight.

Although I am sure most indicators will work as long as they have the mounting bracket on the back and you use the included probe extender so it clears the print head. :D
