The free floating spiral is hard to print without supports since it is not attached to anything. With supports, it is hard to get supports off without breaking the spiral. Nice idea but hard to get a good print. I would like just the piece without the spiral. UPDATE: perhaps you should share any specific parameters to change to succeed in the print.
very cool but the vibration of my bambu a1 caused some blemishes on one of the arms towards the top. At the top of the print the unsupported arm shakes a lot.
