Calibration Rings

thingiverse

Test rings for X and Y calibration are available in various sizes ranging from Ø40 to Ø110 with squares inside. These test rings can be stacked on top of each other on the printbed without touching, sharing the same coordinate for all centers. Initially, I achieved accurate calibration at a single point, but this led to complications, prompting me to verify a broader range of measurements. The text printed on the top surface serves as a convenient reminder of size and orientation.
