Dial Indicator - Mechanical (0-10mm)

This is a model of a mechanical dial indicator (0-10mm). It is not meant to be printed but as a design aid. I have included the SketchUp file and the STL.
In the SketchUp file, if you ungroup the model, the plunger is a separate group that can be moved back and forth along the axis defined by the line above the plunger.
