Question

Is there any trick to remember the examples of the seven primitive unit cells?​

Answer 1

Answer:

I honestly don't know of any "trick" to make this task easier. When I started learning crystal structure, I had a definite weakness in 3D thinking. I had to spend a great deal of time drawing and re-drawing, examining physical models, and rotating them physically, on paper, and mentally before I became truly comfortable with recognizing unit cells and their variations.
