About this model

This is a hollow 20mm cube for calibrating your 3D printer! Cubes are hugely popular to calibrate axis linear travel, but this hollow design also allows you to also calibrate bridging and extrusion flow, all while cutting down the amount of time and filament used for your print. It has 1mm thick walls on all sides, measures exactly 20mm on all the outer faces, and has a hollow interior, all without the need of any support material. Head over to the 'Instructions' tab to get started. Got the cube to print nicely? Check out my Bridge Calibration Object for even more bridging calibration. Wanna remix it? Fire up 'Customizer' and make a cube of your very own!
