I modelled this in Blender.
It's printed with a 0.4 mm nozzle, 0.2 mm layer height and no supports.
There's not a lot of room for infill, but I used 10%.
The model includes a base which is made so that it is stable on the print surface.
It needs to be cut off as shown on the last shot.
There's also a hanger stl in a separate file.
You might also use a 10mm metal bauble hanger like i did on the first shot.
The author marked this model as their own original creation.
