T-Trak Track Alignment Gauge

**T-Trak Track alignment gauge**

This is a gauge for aligning tracks to the T-Trak module standards while constructing modules. The standards call for the centerline of the front track to be 2" from the front edge of the module, the tracks to be placed on 33mm centers, and to overhang the ends of the module 1mm. This gauge can be clamped to the end of a module, with one edge even with the front of the module to achieve this position.

Several years ago I fabricate this style of gauge for my own use from sheet styrene, this is a 3D printable realization.

There are four versions here:

* The normal one
* A version for Kato Unitrack double track pieces that omits the center spacing piece.
* A test version without most of the clamping surface. This prints more quickly, if you want to check that dimensions are correct on your printer.
* A version with three track locations. Useful if you add a third track, or to set the three allowable position used in my narrow single track m
