Pinch Stick/DiagonalGauge/SquareChecker - Rockler T-track

While building some cabinets I was having difficulty using my tape measure to determine if the build was square.  A Pinch Stick was what I needed.

I had a 4' piece of Rockler T-track in the corner, an idea (for the moment), and a 3D printer.

You'll need two on inch ¼" x 20 bolts and two ¼"-20 nuts to clamp the ends where you need them.

I've included the .f3d file so changes can be made to accommodate other T-track sizes.

Once made I was able to ensure that the casework was square before finishing assembly by slipping the pointed part in the diagonals and seeing that it was a smooth slip fit in both directions.
