3D iPhone Customizer App

I’d like to start off by apologizing if this is in the wrong section - I wasn’t exactly sure which section to put it in so I chose the most populated one.

I’m working on an electronics repair/customization website. What I’d like to achieve is to have a 3d model of an iPhone that is customizable via buttons. I’d like the user to be able to customize the color of different sections of the iPhone that can be customized IRL (home button, screen, housing, frame, etc.). I’d also like the 3d model to be rotatable.

I’ve downloaded a couple free 3d models of iPhones but I’m not sure where to go from there.

I’d also like this app. to be accessible via mobile iPhone site - so if there’s another software that I should use (flash support on iPhone?) to make it easier in the long run please let me know. Thanks for any support!
