A long time ago I kit-bashed a Games Workshop Leman Russ Model to have a WW2-style supported suspension. It didn't quite turn out like I wanted it to, so when I learned 3D modeling I mocked up the model I really wanted.
It actually seems like printing this model would be more expensive than the kit bash, but it's really great for learning about digital manufacturing.
