XYZ 20mm Calibration Sphere

thingiverse

Today I learned the hard way that printing a sphere-like object is extremely challenging! My attempt looks more like an egg than a perfect sphere. This means that not only does the general calibration need to be spot on, but also the supports must be meticulously set up. With this sphere, you can experiment with various parameters such as adjusting the number of perimeters and testing whether automated or manual support generation yields better results. You can even try adding supports to only one side of a particular axis, like the left side of both the x- and y-axis, while omitting them from the right side. This approach allows you to achieve conclusive results with just one print, eliminating the need for multiple prints. To change your settings, please refer to the original calibration cube for more information on how to do it correctly. It's worth noting that most slicers enable automatic brim generation by enabling skirt/brim and setting the distance to 0mm. However, if this doesn't work as expected, I've included a second version with a 20mm brim as an alternative. First Test Results: 1st quarter: minimal supports 2nd + 3rd quarter: no supports at all 4th quarter: extensive support To prevent overheating during multi-part printing, consider the following tips: Reduce your printer's temperature and printbed temperature. Install an additional part cooling fan or even use a hand-held ventilator from summer.
