Interesting you should say that.
Over at TES Alliance we're about to open a way to make a clutter resource kit, filled with volunteers' models/textures/etc of these kind of little clutter items people crave. And we'll be taking requests for any of the modelers out there to work on (we already have a request thread and InsanitySorrow is pumping out resources like crazy). Myself, I'll be working on cutting up a cart wheel into various stages of brokeness for random clutter.
If you have specific requests, come see us some time.
