Ornament Sphere

Hello I am new to Cad design I though I would try to make a holiday ornament. I end up with 3 designs.

ornament 1: no supports needed very simple print took about 4 hours.

ornament 2: this will need supports for the rod going through the middle as all the rings other then the last 2 will spin around. I used tree supports

ornament 3: no supports needed, you will need 2 x ornament 3(A) as that is the rod with 1 x ornament 3 (B). you can use just 1 rod but it is a tight fit, i just alternated every second ring to get 2 ornaments in the end.

all parts were made with tinker cad.
