Axis Aligner for Ultimaker

thingiverse

Each notch on this pulley rotates it by 60 degrees. To check if your axis is square, print one of these parts and assess its movement with two hands. A well-aligned 6mm axis should remain stationary; for further calibration, you can print two pieces. Ensure you use a slicer capable of filling thin walls during printing. Clean the holes using a 6mm and 8mm drill bit after printing. For more detailed instructions on aligning your axis, refer to this Ultimaker guide: http://wiki.ultimaker.com/Calibrate
