Simple Inventory for imported FBX.

Hi,

I would like to make simple inventory with imported FBX models.
I have created the inventory script, but I don't know how can I add models to inventory.
I have seen many tutorials and tried inventory systems, but I didn't solved.

Need I make icons the my models?
Need I make prefabs for all imported models?

If anyone have time to help me, than I would be happy.
Thanks.
