XYZ 20mm 3D printer Calibration Cube

myminifactory

Here's a straightforward cube to calibrate your 3D printer. This cube is 20mm on each side, and it's the perfect tool to calibrate the steps per mm for all of your axes. Simply print out the model, and once you've done that, you'll be able to adjust your Steps per mm in your printer's firmware if your 3D printer allows it. To make the necessary adjustments, follow this simple formula: (e/o) x s = your new number of steps per mm. Here, e stands for expected dimension, o represents observed dimension, and s is the current number of steps per mm. This guide shows you how to make a 3D printer calibration cube using Freecad. So why not give it a try? Once you've mastered this technique, you'll never need to buy dice again!
