3D Printer XY Axis Skew Test

This is a very basic skew test for the XY axis on your printer. designed to use minimal filament and keep structural shape.

The file measurements are for the DIAGONAL not the square sides. The protruding flat corners are designed so that the edge should measure the exact corner to corner distance of the square. Do not measure the flat edge of the square using the protrusions, measure the flat section directly behind them.

The corner with the dot needs to be aligned closest to the zero point on your printer, if it is one of the corners. that is there as a reference so you know what direction you printed it.

Take the following steps to get the bed skew in the XY plane:
* 1. Print a test square
* 2. For XY_DIAG_AC measure the diagonal A to C
* 3. For XY_DIAG_BD measure the diagonal B to D
* 4. For XY_SIDE_AD measure the edge A to D
