Include 3D Models for the Arduino Models (Help Wanted!)

[Alarm-Siren]

I would like to add suitable 3D models for each module, but unfortunately I have literally no 3D modelling skills of my own. I have also not had much luck finding suitable existing models to recycle - the few I've found are either in an unsuitable format, or are not available under an appropriate license for inclusion in this library.

If anyone would like to step up to this task, your contributions will be gratefully received.
