Assuming the project is now developed and the necessary critical decisions are already being made. Fig. 4 (above) shows a sample of how the working drawing fror the Lid and the Tray design may look like.
Nothing beats a final rendering of the product in use and showing how it could be used. Fig. 6 shows a very simplified presentation of the Tissue Dispenser in its Front View, followed by a 3D drawing showing how it might be used: Where the tissue paper packet is going to come out, and where the wallet and the phone is going to be placed. Short of how to replenish the tissue paper packets when supply runs low. But that one I hope you will be able to manage. Right?
