A simple calibration cube

A simple calibration cube for both XY contour and hole diameter calibration. There seemed to not be a really simple and fast calibration cube available for both, XY contour and hole diameter calibration for people using metric system in MakerWorld. I also am not really a fan of the “X”, “Y” and “Z” markings on the sides of calibration cubes available as they seem to affect the measuring results a bit, so I created a blank model. Use the small line on top layer for aligning with certain axis (It is aligned with X-axis default on .3mf), so you know which axis' dimensions (X or Y) are off. 3D model dimensions: 20.00 x 20.00 x 20.00 mm. Hole diameter 12.00 mm. How to:Load your machine with filament with low shrinkage % (prefer PLA).Print the cube with your default settings (e.g. I used 0.2mm layer height, 3 walls, 5 top/bottom layers, 15% gyroid).Measure the printed cube with a caliperCompare your measure results with the 3D model dimensions mentioned above(If dimensions are too much o
