CNC Tramming Tool

The CNC Tramming Tool is a simple 120mm object with two holes – 1 for a ¼" end mill, and the other for the 8mm shaft of a dial indicator.  It is used to tram your CNC to ensure the router/spindle is as perpendicular to the build surface as possible.

I've included the FreeCAD 0.20 file in case you need to tweak the settings for hole diameters.   They are clearly listed in the spreadsheet in FreeCAD.

I used PETG at 30% gyroid infill for my print.
