Save the filament for something useful instead.
If seeking to sort out linear dimension accuracy on a 3D printer, it might be an idea to avoid sharp-cornered calibration cubes, such as the one in the photo, and go for something with rounded ...
3D printing specialists are emphasizing that consistent maintenance and calibration often yield better print quality than rushing to upgrade hardware. Guidance includes stabilizing and cleaning ...
