Building Block as a Calibration Cube

We all print calibration cubes at some point, so why not print one that can be used afterwards?

Here we have a simple 2x2 standard square building block.

All dimensions are multiples of 0.4mm so can be printed with a standard 0.4mm nozzle.

Dimensions:
1. Width: 16mm (should be as close to perfectly square as possible)
2. Sidewall height: 9.6mm
3. Height of brick to top of studs: 11.2mm
4. Width of top studs: 4.8mm
5. Sidewall width: 1.6mm
6. Diameter of inner column: 6.4mm
