Hollow Calibration Cube

thingiverse

A 20mm hollow cube is provided for accurate calibration of your 3D printer. Popular for axis linear travel calibration, this cube also allows you to adjust bridging and extrusion flow. It features 1mm walls on all sides, measuring exactly 20mm on each face, while its interior remains void without requiring support material. To start, download and print the cube. Measure the sides and fine-tune your stepper motors' settings accordingly using firmware adjustments. Inspect the roof for bridging speed adjustments. You could even pause a print to measure wall thickness for extruder steps optimization. Repeat these steps until you achieve a perfect 20mm cube, then share your success by posting a picture under the "I Made One" tab! Additionally, check out the Bridge Calibration Object for more bridging calibration options or customize the cube using the 'Customizer' feature.
