Grandma's Favorite Calibration Cube

Here is an updated version of a calibration cube 20x20mm with 10x10mm windows.

This is my second creation and I hope you are happy with it. It uses about 3-4g filament at 15% infill and 2 walls.

Have fun printing and show me your makes.

If you are satisfied with the test, i would be happy about a coffee
