Why just have a Christmas Bell or Christmas angel when you can have both, here we have a Bell Angel and it has wings as well, this would look great hanging from any Christmas Tree.
The bell was designed in Fusion 360 using the revolve tool then a sphere was added for the head, and then a free Angel wings SVG was sourced, imported into Fusion 360 and then extruded and scaled to the correct size, I've printed this one in a single colour but different colours could be added.
Support from the build plate only for the wings.
Thanks for looking.
