My wife has many friends but she also has her 2 bestie's, these Best Friends Forever Christmas Tree Baubles are especially for them, Happy Christmas on one side and Best Friends Forever on the other side, the spheres are a push together snug fit but can be glued together and they can be used on their own of course with no band, if not glued, treats could be placed inside, be careful with the eye where you would fasten the lace or string or whatever you will use to hang these as these can be quite delicate until completely cured, that's when using the BambuLab Gold Silk filament which I found with these, alternative coloured PLA may be different.

The baubles do have the inevitable seam, I put this in between the letters on the band.

The sphere in this case is in Gold Silk as is the band and the band letters are in white.

Support is used from the base up on the bottom and top halves of the sphere, I printed the band separate to the sphere halves.

Another cool project designed with Fusion 360

Thanks for looking
