Christmas Baubles (with Fusion 360 source)

Print the baubles in vase mode, print the hanger cap normally. 3-4 base layers should be sufficient to keep the bauble from delaminating when removing it from the bed. Use your favorite glue to adhere the cap to the baubles.

Each bauble was created using the included Fusion 360 design. The basic approach was to use Fusion's surface modeling tools to create a spiral, then sweep a star shaped path along that spiral. The document is parametric, but you may have to correct the references if you change the profile.
