Calibration Test
In addition to being a practical accessory, this design can serve as a print test to evaluate:
- Dimensional accuracy (e.g., outer diameter and fit on spool/rod).
- Wall adhesion and smoothness.
- Printer's extrusion consistency with thin walls.
- Printer's maximum speed, jerk and acceleration.
- Test for new filaments or new colors.
