I'd love to see pictures of your prints! My Tevo Tarantula can't do it justice!
The tolerances on this model are such that if you want the parts to move you need to print it with a small nozzle at 1 mm layer height, or scale up the model.
This model should fit right in with agepbiz's Tiny Wheels collection.
0.1mm layer height, from a .25mm nozzle.
