Does such a thing exist? I've been looking and I can't find one. I need one to render a two large models for my new game, as I think it would be a pretty cool technology demonstration in a 3D platformer. Anyway, does one exist? If not, does anyone know how to do so?

You already have your 3d models and you want to render them into images that then can be used as sprites?
In 3d Studio Max (which is free for students) that's pretty easy. Just set the self illumination to 100%. In Blender it is probably just as easy.

If you want to render the objects real time (in the game), have a look at the tutorials of @TheLogFather.

What technology do you actually want to demonstrate?

The 3D capabilities of Scratch.
