3D model description

This calibration cube is hollow with square, circular, and hexagonal openings.

With it, you can easily estimate common overhangs (a square rotated 45 degrees, with a hexagon providing 30 degrees of overhang), as well as the dimensions in three axes (20 millimeters).

3D printing settings

Print at any resolution or infill level, no supports required, with at least 2 wall layers/3 layers.

If you have concerns regarding smaller wall dimensions, please increase the print size according to the following ratio:

125% - 25 millimeters
127% - 1 inch
150% - 30 millimeters
