This is a remix of the Wind Spinner by cowtown. I scaled it down slightly to fit within the X1C build volume.
It prints without supports. I used a screw eye from a Harbor Freight kit to attach the string. A screw eye from a picture hanging kit should also work with a bit of glue. For my print I used MatterHackers Quantum Raspberry Gold 2-color PLA. This adds a nice color changing effect as the object spins.
