Old fashion Rutherford's atom planetary model.
I'm afraid that the "new" quantum model cannot be done in a 3D model. There's no way to model probability clouds.
I want you to know that I have another version (better, in my opinion), with a base. It's the one I bought and the one you can find pictures of it, plus the electrons are well-placed:
5.154 w x
7.214 d x
2.029 w x
2.84 d x
