I split the original model by PhantomJM so that it could be printed bigger :)
My print was done on an Anet A8 (It was just posed on the Ender 3 for the picture as there was more light there :) ) at 0.16 layer height and 75% scale. It is just under 16 inches tall. Joined with ABS glue and then sprayed with Rustoleum direct to plastic black gloss. Highlighted with Games Workshop Citadel silver paint and bright orange acrylic paint. I have since clear coated it with Rustoleum Crystal Clear semi gloss and it looks amazing!
I take no credit for the models.
