Video guide & overview:

I bought the case and screen protectors (6-in-1) for a combined price of £7.50 (prices may fluctuate)
–Link to Amazon, to the Terrapin 6-in-1 screen protectors
–Link to Amazon, to the case from the Qubits range (with screen protectors)

The space in-between the case and the Digizoid ZO2, is a 3M Dual Lock SJ3540.

Here are pictures of the screen protector and the case:
