Simple atom modell for my wife to use at school. Very simple, but more visual and haptic than a printed diagram.

Several effects can be described:

• Generation of x-ray radiation
  • characteristic radiation
  • bremsstrahlung
• Compton scattering
• etc.

Obviously the sizes are not to scale…

Print in PLA. The electrons have a flat base by design, easier to print without support and they don't roll all over the table…
