While starting a new woodworking project I noticed I needed to adjust the alignment of the blade and fence on my Ridgid R4512 table saw. I purchased a Digital dial gauge and decided, rather than build a mount out of wood, I would 3D print one. Attached is the result.

It is sized to fit in the 3/4" miter slot on the table surface, engaging about 1/2 the travel on the gauge plunger at the saw blade. This allowed me to measure each edge of the saw blade to determine the required adjustment.
