Printed mine at 175% scale, near the max of what my Ender 3 can do. Printed it hollow with 4 lines thick wall at 0.12mm layer height. It prints OK without supports, but for me the underside of the tail and right ear came out rather rough and could probably have benefitted from some ro cut down on postprocessing.
In either case, after some sanding and painting it's an absolutely great and hilarious model. Love it!
