Bloch Sphere Model

I used a 140mm transparent christmas ball and put everything in.
The coordinatesystem in the pictures is lasercutted and colored with a pen, but you can also 3D print it. For that I recommend to use different colors.

The arrow is made with to magnets (5mm diameter and 5mm height) that are printed into the arrow and the button.

Printing the coordinate system:

1. start with outside color (for example white)
2. make colorchange at 0.5mm (latest at 0.75mm) to the lettering color, for example to black for a good contrast
3. make colorchange at 2.5mm (earliest at 2.25mm), back to the outside color (for example white)

Printing the coordinate system tags:

1. start with outside color (green, blue, red)
2. make a colorchange at 0.5mm (latest at 0.75mm)

Printing the arrow and the button:

1. start printing
2. pause at ~5.75mm put in the magnets
3. go on with printing

→ Have fun!
