Simple spherical christmas tree ornament.
Choose size, number of "ribbons" and choose to have one helix or two running in different directions.
Should print without support and the small flat base should be sufficient to get good adhesion to the bed.
At least with PLA it is best to print two or more at once so that, especially for the top ring, there is more time for the PLA to cool down.
The thing pushes overhangs quite far to the limit, but with low temperatures (I had 190Â°C) it should work.
I printed with 1 shell and 25% infill, but there almost is nothing solid.
